## What would be the maximum tensile stress induced in the 0.050-inch-thick steel band during the braking period if the drum were brought to a stop in exactly one revolution?

1.A simple band brake is constructed using a 0.050-inchthick by 2-inch-wide steel band to support the tensile forces. Carbon-graphite material is bonded to the inside of the steel band to provide the friction surface for braking, and the rotating drum is to be a solid-steel cylinder, 16 inches in diameter and 2 inches in axial thickness. The brake band is wrapped around the rotating drum so that it is in contact over 270 of the drum surface. It is desired to bring the drum to a complete stop in one revolution from its operating speed of 1200 rpm. What would be the maximum tensile stress induced in the 0.050-inch-thick steel band during the braking period if the drum were brought to a stop in exactly one revolution? Assume that the rotating drum is the only significant mass in the system, and that the brake is kept dry.
