The force P applied to the brake handle enables the band brake to reduce the angular speed of a rotating drum. If the tensile strength of the band is 3800 lb, find the maximum safe value of P and the corresponding braking torque acting on the drum. Assume that the drum is rotating clockwise.
A uniform plank is supported by a fixed support at A and a drum at B that rotates clockwise. The coefficients of static and kinetic friction for the two points of contact are as shown. Determine whether the plank moves from the position shown if (a) the plank is placed in position before the drum is set in motion; and (b) the plank is first placed on the support at A and then lowered onto the drum, which is already rotating.
The square-threaded screw with a pitch of 10 mm and a mean radius of 18 mm drives a gear that has a mean radius of 75 mm. The static and kinetic coefficients of friction between the gear and the screw are 0.12 and 0.06, respectively. The input torque applied to the screw is C0=10Nm. Assuming constant speed operation, determine the output torque C1 acting on the gear.
A flat belt passes over two idler pulleys and under a rotating drumof diameter 8 in. The axle of the drum is free to move vertically ina slot, and a spring keeps the drum in contact with the belt. Whatis the minimum force which should be exerted by the spring if slippageis not to occur when a 30-lb · ft torque is applied to the drum? Thecoefficient of static friction between belt and drum is 0.30 and theangle of contact is 180 degrees.
