Answer is:
No
Explanation:
The ratio between the velocities of driver pulley and driven pulley is known as velocity ratio. Due to slip of belt, the velocity ratio of the belt drive decreases.
Answer is:
Three times
Answer is:
Uneven extensions and contractions of the belt when it passes from tight side to slack side
Explanation:
In Belt drives when the belt passes from the slack side to the tight side a certain portion of the belt extends. Similarly when the belt passes from the tight side to slack side it contracts. Hence creep in belt drive is due to uneven extensions and contractions of the belt when it passes from tight side to slack side.
This phenomenon of alternative stretching and contraction of the belt results in relative motion between the belt and the pulley surface. This relative motion is called creep.
