Question

boy uses a simple pulley to pull a block up a ramp. The height of the ramp is 4 m and the length of the ramp is 10 m. Calculate the mechanical advantage of the ramp and does the pulley provide any additional advantage?

Answer 1

(a) The mechanical advantage of the ramp is determined as 2.5.

(b) The pulley provides additional advantage since it assisted the boy in pulling up the load.

What is mechanical advantage?

The mechanical advantage of an object is the ratio of output force to input force, hence it is called force ratio.

Mechanical advantage of the ramp

M.A = Lp/h

where;

• Lp is the length of the inclined plane
• h is height of the inclined plane

M.A = 10/4

M.A = 2.5
