An inclined plane is used to lift a box into a moving truck. The ramp is 6m long and 1.5m from the ground. What is the mechanical advantage of the inclined plane?

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 :

Putting given values in above equation, we get :

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

this is a good question! i'll do some research and come back when i have the answer!

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
