Foreign material on a belt causes glazing.

• T

• F

Flat belts are used to drive a wide range of industrial machinery and vary in width and thickness depending on the torque requirements.

• T

• F

S-belts can provide more efficiency than V-belts by combining the advantages of a flat belt drive system and a positive synchronous drive system.

• T

• F

A pulley system depends on friction between the V-belt and the sheave.

• T

• F

Belt speed can be calculated when the motor speed and diameter of the motor sheave are known.
