(a) more than 1,

(b) equal to 1, and

(c) less than 1?

Solutions:

(a) When the mechanical advantage is greater than one, the lever acts as a force multiplier, allowing us to overcome a big resistive force with little effort.
(b) When the mechanical advantage is 1, the lever has the same length effort and load arms.
(c) When the mechanical advantage is less than one, the speed is increased by using levers. This indicates that the load displacement is greater than the effort displacement.
