Question

Class II levers are designed to have :

(a) M.A = V. R. (b) M.A > V. R.

(c) M.A. > 1 (d) M. A. < 1

Answer 1

(c) M.A. > 1

Resistance (or load) in the middle: the effort is applied on one side of the resistance and the fulcrum is located on the other side, for example, a wheelbarrow, a nutcracker, a bottle opener or the brake pedal of a car. Load arm is smaller than the effort arm. Mechanical advantage is always greater than 1. It is also called force multiplier lever.
