A simple band brake has a 76 cm drum and fitted with a steel band 2/5 cm thick lined with a brake lining having a coefficient of friction of 0.25. The arc of contact is 245 degrees. The drum is attached to a 60 cm hoisting drum, that sustain a rope load of 820 kg. The operating force has a moment arm of 1.50 m and the band is attached 12 cm from the pivot. Find the width of a steel band for a tensile stress of 50 MPa.

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
