各 creativity 創造力1.1945-1949: The immediate years after the Second World War ● At the end of 1945, Mao Zedong had come to see the USA as the greatest threat to his aspirations. a. He understood that East Asians were looking to the USA as the true liberator from Japanese imperialism. b. The USA’s support for the Kuomintang(KMT) and the restoration of U.S. authority in formerly Japanese Manchuria clashed with the CCP’s plans to use the region for its own needs in the impending civil war between the CCP and the GMD. ■ To compound matters, while the KMT was recognised internationally as the official government in China, Mao and the CCP saw the party as a puppet of U.S. imperialism. ● While Mao saw the USA as the greater threat to the CCP’s plans, Soviet actions also frustrated him. a. The USSR provided minimal and incoherent support for the Chinese Communists in Yan’an and Manchuria. b. Stalin also attempted to extract territorial and economic concessions from the Guomindang government in the Friendship and Alliance Treaty China signed in August 1945 under American and Soviet pressure in exchange for Soviet entry into the Second World War against Japan. ● The emerging superpower conflict over Europe and over American intervention in the impending civil war in China led to Mao’s ideological perception of the 8838/01 H1 History Paper 1 Theme II: The Cold War and East Asia (1945-1991) \ Page | 8 USA as an aggressive imperialist power that was hostile towards other countries, especially the USSR and China. ● In 1946, Mao promoted the theory of the intermediate zone, which envisioned a global united front against American imperialism. a. Mao saw the emerging superpower conflict as an American-Soviet contest for the intermediate zones, the capitalist, colonial and semi- colonial countries of West Europe, Africa, and Asia. b. Mao believed that the USSR was the defender of world peace. c. The intermediate zone, which included China, would not be part of the socialist camp. d. Despite the tremendous potential that U.S. aid held for China’s reconstruction, Mao’s ideological worldview and the impending civil war against the Guomindang prevented him from seeking normalised relations with the USA. In 1949, Mao decided to lean towards the side of the USSR despite two decades of unreliable support from them. e. Mao saw the anti-bourgeois campaigns in East Europe as evidence that China should isolate capitalist-bourgeois forces within it.2 f. Stalin had expelled Yugoslavia from the socialist camp as its leader, Tito was seen to have directly challenged Stalin’s authority. ■ Mao thus saw it as imperative to stress close unity to the USSR lest he was seen as a second Josip Broz Tito. At the same time, Mao sought a loose partnership with the USSR because Mao believed that China should preserve a high measure of self- reliance and zili gengsheng (自力更生) (regeneration through one’s own efforts). ● When the People’s Republic of China was formed on 1 October, 1949, relations between China’s and the USSR’s communists had improved substantially. a. However, the Chinese Communist Party (CCP) was also aware that the USSR never treated Chinese interests as a priority. What the CCP failed to fully understand was that Stalin ruled East Europe much like it was his empire and how this would have implications for China. b. In Mao’s first visit to the USSR in December 1949, Stalin was non- committal regarding the interests raised by the Chinese, and treated Mao as an underling as he feared that closer relations with the PRC would cause the USSR to lose privileges gained from the KMT. _________________________ 2 What Mao did not realise at that point was that the anti-bourgeois campaigns in East European countries were part of Stalin’s intentional design to consolidate the power of communists in them. 8838/01 H1 History Paper 1 Theme II: The Cold War and East Asia (1945-1991) \ Page | 9 A note on Sino-American relations 2. Early 1950: The USA’s hands-off policy towards Taiwan begins to change ● By early 1950, the Truman administration had written off Taiwan and believed it was only a matter of time before the island fell to the PLA. ● Two events in early 1950 changed the USA’s position on East Asia. ○ The formation of the USSR-PRC alliance in February 1950 ○ The North Korean invasion of South Korea in June 1950 3. 1950: The Sino-Soviet Friendship, Alliance and Mutual Assistance Treaty ● Signed on 14 February, 1950. 3.1Implications for Sino-Soviet relations ● Stalin saw it as a means to get concessions that he had failed to get from the Kuomintang (KMT) government in 1945. ● For Mao and the newly founded People’s Republic of China (PRC), the alliance would provide security against U.S. imperialism and allow the PRC to get economic aid for reconstruction from the USSR. ● The Chinese realised soon after the 1950 treaty had been signed that the Soviet Union was intent on exploiting the agreement in its own favour. 8838/01 H1 History Paper 1 Theme II: The Cold War and East Asia (1945-1991) \ Page | 10 ● The Sino-Soviet alliance was officially directed against Japanese militarism and its allies, especially the USA. ● The Sino-Soviet alliance comprised three elements: party, military and economic relations. ○ Party: The Chinese Communist Party (CCP) was included in the customs of communist party internationalism, such as regular exchange of party delegations to congresses of the fraternal parties in Stalin’s socialist camp. ■ This move was meant to bring the PRC’s ideological beliefs about communism into greater alignment with the USSR’s. ○ Military: The alliance was supposed to provide the newly formed and weak PRC with a strategic deterrent and military aid against the USA on three fronts: Guomindang-held Taiwan, divided Korea, and Vietnam where France attempted to reestablish its colonial control. ■ Convinced that the USA would aggressively seek ways to undermine the CCP-led PRC through Taiwan, Korea and Vietnam, Mao sought an active defence. ● While in Moscow, Mao unsuccessfully asked Stalin to provide military assistance for the liberation of Taiwan. ● At the beginning of 1950, the PRC delivered large-scale military aid to Hanoi. The PRC was the first country to grant the communist-led Democratic Republic of Vietnam diplomatic recognition on 18 January 1950; Mao persuaded Stalin to do so on 30 January 1950. ● The PRC committed itself to North Korea, where Mao saw the commitment to North Korea both as a defence against U.S. imperialism and as support for a fellow communist country. ○ Economic: During Mao’s first stay in Moscow, Stalin had personally promised the delivery of fifty projects for primary industrialisation. ■ The agreement also led to a series of supplementary ones, such as a US$ 300 million loan that the PRC would repay with a mixture of strategic materials, rubber, agricultural products, goods for daily use and hard currency. ■ Significantly, Stalin used Soviet military and economic aid to extract concessions similar to those he failed to get from the Guomindang government in 1945. ■ The USSR and PRC would disagree on the pace and extent of the PRC’s planned development. ● In the last five weeks of Stalin’s life in early 1953, he attempted to pressure the PRC to reduce the planned 8838/01 H1 History Paper 1 Theme II: The Cold War and East Asia (1945-1991) \ Page | 11 development speed to a mere annual growth of 13-14 percent, and to plan individual projects in detail beforehand. These moves would potentially result in the PRC’s economy growing at a slower rate than initially projected. ● However, after Stalin’s death on 5 March 1953, the PRC’s Zhou Enlai decided to use his visit of condolence to the USSR to press forward negotiations. ○ When talks resumed in 1 April 1953, Beijing pressed for 150 Soviet industrial projects, but Moscow reduced them to 91 on the basis of insufficient data provided by the Chinese. ■ The economic disarray after China’s civil war and the economic pressures that came with the Korean War influenced recovery and reconstruction in the early years of the PRC. ● Despite the PRC being unable to tap into Soviet economic assistance immediately, mutual trade between China and the USSR nevertheless increased 6.5 times from 1950 to 1956. ● Together with the 50 projects promised by Stalin in 1950, the final version of the First FYP for the PRC included 141 Soviet and 68 East European projects in a total of 649 planned. Three thousand Soviet advisers sent to China in subsequent years were directly linked to the First FYP. ● By 1955, over 60 percent of China’s goods exchange was with the USSR. ● Soviet economic assistance to China added up to the largest foreign development venture in the socialist camp ever. ○ The total number of planned projects amounted to between 300 and 360 projects. ○ However, the number of total finished projects ranged between 134 and 150. ● Transfers of knowledge and expertise were important to China’s economic development. ○ A study on Soviet experts counts 1,445 political advisers and 9,313 technical specialists sent to China until their sudden withdrawal in mid-1960. ■ For political reasons, the gradual withdrawal of advisers began after late 1956.Что называют простыми механизмами Умение облегчать себе труд с помощью технологий отличает человека от животного. Тысячи лет назад наши предки научились мастерить простые механизмы, которые способны увеличивать усилие, а также изменять направление прикладываемой силы. Принципы их работы лежат в основе любого орудия труда — от садовой лопаты до подъёмного крана. Простые механизмы — приспособления, служащие для преобразования вектора силы по величине и/или направлению.

Виды простых механизмов Наклонная плоскость и её разновидности: клин и винт. Рычаг и его разновидности: блок и ворот. Теперь расскажем, как они работают. В этой статье мы рассмотрим действие идеальных механизмов, в работе которых не учитывается сила трения. Работа простых механизмов Наклонная плоскость Подниматься по пологому склону горы легче, чем карабкаться по отвесной скале. Чем меньше наклон — тем легче его преодолеть. Это нехитрое наблюдение помогло людям создать простой механизм — наклонную плоскость. Допустим, нам нужно поднять груз на определённую высоту. Конечно, можно сделать это непосредственно. Поднятие груза на высоту Правда, если груз большой, приложить достаточную силу будет нелегко. Но если поставить его на лёгкую тележку и вкатывать по наклонной плоскости, то понадобится гораздо меньше усилий. Наклонная плоскость Чем меньше угол наклона плоскости, тем больше выигрыш в силе: k = l / h. Чтобы просто поднять груз весом в один килограмм, требуется усилие: F1 = mg = 9,8 H. Теперь посмотрим, какое усилие понадобится, чтобы поднять этот груз на один метр, используя наклонную плоскость длиной десять метров: Использование наклонной плоскости позволило нам выиграть в силе в десять раз. Но путь, который нам пришлось пройти с грузом, также увеличился вдесятеро.

Рассмотрим топор: его лезвие — это клин, боковые поверхности которого сходятся под острым углом, образуя наклонные плоскости. Когда мы вонзаем топор в полено, эти плоскости с огромной силой раздвигают волокна древесины и заставляют полено расколоться. Клин При ударе сила P вгоняет топор в дерево, и на его лезвие действуют сдавливающие силы F со стороны полена. Проекция каждой из сил F на плоскость симметрии лезвия (AB) равна Fsinα. Поскольку они действуют с двух сторон, условие равновесия сил таково: P = 2Fsinα. Чем длиннее и острее клин (то есть чем меньше угол), тем меньше может быть P по отношению к 2F. Угол лезвия обычного колуна — около 25°, соответственно, сила Р примерно в пять раз меньше, чем 2F. Иными словами, чтобы расколоть полено, нужно приложить в пять раз меньше усилий, чем требуется, чтобы разорвать его. Люди пользуются топорами уже более 9 тысяч лет. Гвозди, иглы и ножи работают по тому же принципу. Клин придуман не человеком, а самой природой: например, клюв дятла легко вонзается в дерево благодаря оптимальной клиновидной форме. Винт Если свернуть наклонную плоскость в спираль вокруг цилиндра — получится винт. Винт Впервые описание винта встречается в работах древнегреческого учёного Архита Тарентского, жившего в V–IV веках до нашей эры. Знаменитый Архимед в III веке до нашей эры создал с помощью винта устройство для подъёма воды в оросительные каналы. Винты широко используют для крепления деталей, бурения отверстий и даже в качестве движителя сверхпроходимых шнекороторных вездеходов. Резьба винта — это наклонная плоскость длиной l и высотой h, свёрнутая в трубочку. Когда мы наворачиваем гайку на болт, мы перемещаем её по наклонной плоскости. Как и в случае с обычной плоскостью, выигрыш в силе равен отношению h к l, но теперь l рассчитывается по формуле длины окружности: l = πD. Расстояние между витками называют шагом резьбы. Чем оно меньше, тем длиннее плоскость и больше выигрыш в силе. Рычаг Простейший рычаг — это палка, способная вращаться вокруг неподвижной опоры. Принцип рычага используется при работе башенного крана, рычажных весов, кухонных ножниц и даже обычной лопаты. Интересно, что кости в наших конечностях тоже работают как рычаги. Рычаг У любого рычага есть точка опоры (О) и два плеча (длины l1 и l2), к которым в точках A и B прикладываются силы. Вращение рычага зависит от приложенной к нему силы и от длины плеча. Чем больше сила и чем длиннее плечо, тем сильнее вращающее действие. Именно поэтому работать лопатой проще, держа её ближе к концу черенка, а нести груз на согнутой руке легче, чем на вытянутой. На рисунке тело А воздействует на рычаг с большей силой, чем тело B, но плечо l1 короче, чем l2, поэтому тела находятся в равновесии. В таких случаях говорят, что моменты двух сил уравновешены. Момент силы — произведение силы на длину плеча: M = F ⋅ l. Рассчитаем моменты силы для обоих тел: MA = PA ⋅ l1 = mAgl1. MB = PB ⋅ l2 = mBgl2. Тела находятся в равновесии, значит, mAgl1 = mBgl2. Чем больше будет длина плеча l2, тем меньшее усилие понадобится, чтобы уравновесить тело A. Так, при достаточной длине рычага можно поднять даже неподъёмный груз. Действие рычага Чтобы просто поднять тело, нужно преодолеть силу тяжести: F = mg. Чтобы вычислить силу для поднятия тела рычагом, нужно приравнять соответствующие моменты сил: mgl1 = Fx ∙ l2. Следовательно, Если l1 больше l2 в пять раз, то: Увеличивая длину плеча, мы выигрываем в силе, но проигрываем в перемещении. Нам удалось уменьшить силу в пять раз, но чтобы короткое плечо рычага поднялось на 10 сантиметров вверх, придётся опустить длинное на 50 сантиметров.

Так называют колесо с жёлобом, в который вложен трос. Если ось колеса зафиксировать, к одному концу троса привязать груз, а за другой тянуть, получится простой механизм — неподвижный блок. Неподвижный блок На груз действует сила тяжести F = mg. Чтобы удержать верёвку, требуется приложить такую же силу. Никакого выигрыша в величине силы неподвижный блок не даёт. Зато можно менять её направление — тянуть верёвку в любую сторону. Если прицепить груз к оси колеса, один конец верёвки закрепить, а за другой тянуть, получится подвижный блок, который позволяет выиграть в силе в два раза. Эффект достигается за счёт того, что блок с грузом поднимают как бы сразу две верёвки: за левую тянет человек, а правую натягивает вбитый в потолок гвоздь. Подвижный блок За выигрыш в силе приходится платить проигрышем в перемещении: чтобы поднять груз на нужную высоту h, понадобится выбрать вдвое большую длину и верёвки: l = 2h. Ворот Ворот издревле применяется для поднятия воды из колодца. К барабану, способному вращаться вокруг своей оси, прикреплены верёвка и рукоять. Когда мы вращаем рукоятку — вращается и цилиндр, а верёвка наматывается на него, поднимая или опуская груз. Ворот Ворот действует по тому же принципу, что и рычаг: плечом силы в данном случае становится рукоятка, а плечом груза — радиус барабана. Чем длиннее рукоять относительно радиуса барабана — тем больше выигрыш в силе. На рисунке длина рукояти равна трём радиусам барабана. Значит, он поднимает ведро с силой, в три раза большей, чем сила наших рук. При этом путь, который проходит рукоять ворота, в три раза длиннее куска верёвки, который в это время накручивается на вал. Золотое правило механики Все примеры простых механизмов, которые мы рассмотрели, имеют одно общее свойство, которое называют золотым правилом механики. Во сколько раз мы выигрываем в силе, во столько же раз проигрываем в перемещении. Произведение силы на перемещение в механике называется работой и обозначается буквой А: A = F ⋅ S ⋅ cos α, где α — угол между векторами силы и перемещения. Если направления векторов совпадают, формула работы выглядит проще: A = F ⋅ S. Сэкономить в силе больше, чем проиграть в перемещении — то есть выиграть в работе — не позволяет ни один механизм. Чем меньше силы нужно потратить при подъёме тела по наклонной плоскости, тем длиннее должна быть эта плоскость. Чем меньше сил нужно для воздействия на рычаг — тем длиннее должно быть его плечо. «Дайте мне точку опоры, и я переверну Землю» — заявил Архимед. Теоретически он мог бы поднять груз, равный нашей планете, выбрав рычаг подходящей длины. Масса Земли — примерно 6 000 000 000 000 000 000 000 тонн, в то время как человек в среднем способен поднять груз около 60 килограммов. А значит, плечо силы должно быть больше плеча груза в 100 000 000 000 000 000 000 000 раз. Поэтому, чтобы плечо груза сдвинулось хотя бы на один сантиметр, учёному пришлось бы сдвинуть плечо силы на 1000 000 000 000 000 000 км. Даже со скоростью движения в 1 м/с на это ушло бы тридцать тысяч миллиардов лет. Ответим9 - 1 (2.1H) SICHERHEIT IM INTERNET9 - 1 (2.1H) Sicherheit im Internet (Aufg. 3)
