In a belt drive, the condition where there is relative motion between
the belt and the pulley surface is known as
बेल्ट ड्राइव में, वह स्थिति जहां बेल्ट और पुली सतह के बीच सापेक्ष गति होती है, कहलाती है
Creep
Slip
Slack
Contact angle
Creep
When the belt
passes from slack side to tight side, a certain portion of the belt extends and
it contracts again when belt passes from tight side to slack side. Due to these
changes in length, there is a relative
motion between the belt and the pulley surfaces.
Hence, the
correct option is (A).
