Question

Steeper the inclined plane lesser its mechanical advantage,explain?

Answer 1

Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved.The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans.

Mechanical advantage = length of the sloped surface/height it spans
