Question

An inclined plane is used to lift a box into a moving truck. The ramp is 6m long and 1.5m

Answer 1

Given :

An inclined plane is used to lift a box into a moving truck. The ramp is 6 m long and 1.5 m.

To Find :

The mechanical advantage of the inclined plane.

Solution :

Mechanical advantage, M.A of an inclined plane is given by :

$M.A = \dfrac{\text{Length of slope}}{\text{Height of plane}}$

Putting given values in above equation, we get :

$M.A = \dfrac{6 \ m}{1.5 \ m}\\\\M.A = 4$

Therefore, the mechanical advantage of the inclined plane is 4.
