Question

The slope of the inclined plane is low, then it is easier to climb up.

• A. Mechanical advantage is equal to the velocity ratio.
• B. Mechanical advantage is always greater than the velocity ratio.

Answer 1

The correct option is A

Mechanical advantage is equal to the velocity ratio.

A leaning ladder, a staircase, a bridge, a sloping wooden plank are all examples of an inclined plane. An inclined plane is a plane surface which is placed at an acute angle to the ground. The smaller the angle between the base and the inclined plane, the greater is the advantage of using it.
