In
belt drives the centrifugal tension
बेल्ट ड्राइव में अपकेंद्रीय तनाव होता है
Reduces the speed of driven wheel
Reduces
friction between the belt and pulley rim
Reduces
the driving power
Reduces
the lengthening of belt under tension
Reduces
the driving power
The
centrifugal force reduces the pressure between the belt and the rim of the
pulley by moving thebelt away from pulley, reducing the wrap angle and hence,
reducing the belt tension and power transmission.
Hence,
the correct option is (C).
