List of top Physics Questions on tension asked in CUET (PG)

A band brake having a bandwidth of 90 mm, drum diameter of 300 mm, coefficient of friction of 0.3 and an angle of wrap of \(270\degree\) is required to create a friction torque of 1000 Nm. The maximum tension (in kN) developed in the band is:

If W is weight of the chain, L is span and P is tension or pull, then sag correction for chain line will be.
