Question

Will the pulley rotate clockwise, counterclockwise, or not at all? Match the words in the left column to the appropriate blanks in the sentences on the right.

A) Clockwise
B) Counterclockwise
C) Not at all

Match the correct rotation direction to each sentence.

Sentences:

The weight is greater than the applied force; therefore, the pulley will _______.
The system is in equilibrium, so the pulley will _______.
The applied force is greater than the weight; therefore, the pulley will _______.

Answer 1

The rotation of the pulley depends on the relationship between weight and applied force. If weight > applied force, pulley rotates counterclockwise. If applied force > weight, pulley rotates clockwise. If weight = applied force, pulley doesn't rotate.

Step-by-step explanation:

The rotation of the pulley will depend on the relationship between the weight and the applied force. If the weight is greater than the applied force, then the pulley will rotate counterclockwise. If the applied force is greater than the weight, then the pulley will rotate clockwise. If the weight and the applied force are equal, the pulley will not rotate at all.
