Answer

Explanation:

Step1: Analyze Pulley 1

As the belt moves to the right as shown, Pulley 1 is a driving - pulley. The side of the belt in contact with Pulley 1 that is moving is the upper side. So, Pulley 1 rotates clock - wise.

Step2: Analyze Pulley 2

The lower side of the belt is in contact with Pulley 2 and is moving to the left. So, Pulley 2 rotates counter - clockwise.

Step3: Analyze Pulley 3

The upper side of the belt is in contact with Pulley 3 and is moving to the right. So, Pulley 3 rotates counter - clockwise.
