Question

A belt passes over a drum and its ends are connected to springs? If the drum rotates in the direction shown and there is friction between the drum and the belt then"

a. The drum will rotate faster
b. The drum will rotate slower
c. The belt will slip on the drum
d. The belt tension will increase

Answer 1

b. The drum will rotate slower. When there is friction between the drum and the belt, the drum will rotate slower.

Step-by-step explanation:

When there is friction between the drum and the belt, the belt will slip on the drum. This is because the friction opposes the motion of the belt. As a result, the belt will not be able to effectively grip the drum, causing it to slip.

This slipping of the belt will lead to a decrease in the rotation speed of the drum. Therefore, the correct answer is b. The drum will rotate slower.
