  • Q5

    Sarah is using a bottle opener to remove a cap. The distance from the fulcrum to where she applies force is 14 cm, while the distance from the fulcrum to the bottle cap is 4 cm. If Sarah applies a force of 15 N and the cap requires 42 N to remove, calculate the ideal mechanical advantage of this lever.

  • Q8

    A construction worker is using a pry bar to lift a heavy concrete slab. The fulcrum is 15 cm from the end under the slab, and the worker pushes down 150 cm from the fulcrum. If they apply 125 N of force and lift a 1125 N slab, calculate the ideal mechanical advantage of this lever.
