Question:medium

The ratio between the tensions in the right side and slack side of a flat belt drive increases

Show Hint

To prevent belt slippage and transmit more power:
Increase the angle of lap (\(\theta\)) by installing an idler pulley on the slack side of the belt.
Because the tension ratio increases exponentially with \(\theta\), even a small increase in contact angle significantly improves torque transmission.

in direct proportion to the angle of lap
proportional to the width of the belt.
exponentially as the angle of lap increases
in direct proportion to the coefficient of friction
