Compound pulley

Correct! Wrong!

In a pulley system, what does the term "idler pulley" refer to?

A pulley that is used to change the direction of force

A pulley used to increase the speed of the driven component

A pulley that has no load and serves to guide the belt

A pulley that provides power to the system

Correct! Wrong!

What is the effect of increasing the diameter of the driving pulley on the speed of the driven pulley in a pulley drive system?

It increases the speed of the driven pulley

It decreases the speed of the driven pulley

It has no effect on the speed of the driven pulley

It makes the system more efficient

Correct! Wrong!

Which of the following factors affects the efficiency of a pulley drive system?
