Question

Mechanical advantage is calculated by using the formula:

a
Length of Slope (L) / Height of slope (H)
b
Normal Force/ Acceleration
c
Height of Slope (H) / Length of Slope (L)
d
Force of Friction/Gravity

Answer 1

The correct formula for calculating mechanical advantage using an inclined plane is:

**a** Length of Slope (L) / Height of slope (H)

So, option **a** is the correct answer. Mechanical advantage in the context of an inclined plane indicates how much less input force is needed to lift a weight compared to lifting it straight up.
