Correct option is D
Creep in a belt drive refers to the gradual slipping or relative motion of the belt over the pulleys due to unequal tension on the tight and slack sides of the belt.
· In a belt drive system, the tight side carries more tension than the slack side, causing a difference in belt elongation and contraction as it moves around the pulleys.
· This results in a small but continuous slipping motion known as creep, which reduces efficiency and power transmission.
· Unlike slip, which is caused by inadequate friction, creep occurs due to elastic stretching of the belt material.
· To reduce creep, high-friction materials like rubber belts and proper belt tensioning techniques are used.
