Question

Select the statements that hold true for a Class II lever.

• A. Mechanical advantage > 1
• B. Mechanical advantage < 1
• C. A wheelbarrow is a class II lever.
• D. Also called an effort multiplier

Answer 1

Answer: (A), (C), (D)

The correct options are
A Mechanical advantage > 1
C A wheelbarrow is a class II lever.
D Also called an effort multiplier

In class II lever, the effort is applied on one side of the resistance(load) and the fulcrum is located on the other side, for example, a wheelbarrow, a nutcracker, and a bottle-opener. The load arm is smaller than the effort arm so the mechanical advantage is always greater than 1. It is also called force multiplier lever/ effort multiplier lever.
