Explanation:
- Belt drives are used to transmit power from one shaft to another.
- When the belt is in motion, it tends to slide over the pulleys due to the frictional force between the belt and the pulley surface.
- The amount of slip that occurs in a belt drive depends on the angle of rest and angle of creep.
- The angle of rest is the maximum angle at which the belt will remain in contact with the pulley surface without slipping, when the pulley is at rest.
- The angle of creep is the maximum angle at which the belt will remain in contact with the pulley surface without slipping, when the pulley is in motion.
- Total slip refers to the difference between the linear distance traveled by the belt and the distance traveled by the pulley surface during a complete revolution of the pulley.
- Total slip occurs when the belt slips on the pulley surface due to insufficient frictional force.
Option A:
- If the angle of rest is zero, it means that the belt will remain in contact with the pulley surface even when the pulley is at rest.
- This indicates that there will be sufficient frictional force between the belt and the pulley surface to prevent slip.
- Therefore, in this case, total slip will not occur in the belt drive.
Option B:
- If the angle of creep is zero, it means that the belt will remain in contact with the pulley surface even when the pulley is in motion.
- This indicates that there will be sufficient frictional force between the belt and the pulley surface to prevent slip.
- However, this does not guarantee that total slip will not occur in the belt drive, as there may be other factors such as belt tension, pulley diameter, and belt material that can affect slip.
Option C and D:
- If the angle of rest is greater than the angle of creep, it means that the belt will slip on the pulley surface when the pulley is in motion, as the angle of creep is the maximum angle at which the belt can remain in contact with the pulley surface without slipping.
- Similarly, if the angle of creep is greater than the angle of rest, it means that the belt will slip on the pulley surface even when the pulley is at rest, as the angle of rest is the maximum angle at which the belt can remain in contact with the pulley surface without slipping.
- In both these cases, there will be insufficient frictional force between the belt and the pulley surface to prevent slip, and total slip will occur in the belt drive.
