- Q1
**the quantity that indicates the ability of force to causes rotation called the**torque

effort

force

lever

300s - Q2
**The physical quantity which causes an object to rotate or move in a circle or change its rotational motion is called**Energy

Torque

Force arm

Force

300s - Q3
**Magnitude of torqueis represented by formula**l + F

l/F

l – F

**l × F**300s - Q4
**Moment of force is equal to**F x d, where F is force and d is distance

F/d, where F is force and dis distance

F - d, where F is force andd is distance

F + d, where F is force andd is distance

300s - Q5
**moment of torque is product of**height of hinge from flour to top

from line of bottom to action of force

perpendicular distance to pivot from bottom

perpendicular distance from pivot and action of force

300s - Q6
**in order to satisfy principle of moment for an objectin equilibrium one needs to make sure that**Sum of clockwise moments about pivot > Sum of anti-clockwise moments about pivot

Sum of horizontal forces =Sum of vertical forces = 0

Sum of clockwise moments about pivot = Sum of anti-clockwise moments about pivot

Sum of clockwise moments about pivot < Sum of anti-clockwise moments about pivot

300s - Q7
**seesaw is equilibrium if sum clockwise equal**sum anticlockwise

sum vertical force

sum horizontal force

300s - Q8
**one can get maximum torque by applying**smaller force on shorter lever arm

larger force on longer lever arm

smaller force on longer lever arm

larger force on shorter lever arm

300s - Q9
**If value of moment arm is zero, then torque produced will be**decreased

doubled

0

1

300s - Q10
**Increasing the moment arm,increases**velocity

axis of rotation

momentum

torque
