A simple band brake has a 76 cm drum and fitted with a steel band 2/5 cm thick lined with a bake 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 sustains 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 point. Find the torque just required to support the load (clockwise).

A flat belt with a width of 120 mm and a thickness of 5 mm transmits power from a driving pulley with a diameter of 250 mm to a driven pulley with a diameter of 700 mm. The mass per unit length of the belt is 2.1 kg/m, and the coefficient of friction is 0.25. The input power of the belt is 60 kW at 1000 rpm. Calculate the following when the center distance is 3.5 m. (a) Maximum tensile stress of the belt(b) Axial load on each pulley
A steel tire, 20 mm thick, 90 mm wide, and 1600.0 mm inside diameter is heated and shrunk onto a steel wheel 1600.5 mm in diameter. If the coefficient of static friction is 0.40, what torque is required to twist the tire relative to the wheel? Neglect the deformation of the wheel. Use E = 100 GPa.
A single-threaded 25-mm power screw is 25 mm in diameter with a pitch of 5 mm. A vertical load on the screw reaches a maximum of 5 kN. The coefficients of friction are 0.06 for the collar and 0.09 for the threads. The frictional diameter of the collar is 45 mm. Find the overall efficiency, and the torque to “raise” and “lower” the load. If the effort load is 75 N, find the force ratio and movement ratio.
I will rate helpful. Thank you.
A block brake with a torque of 250 N-m. Its drum rotates at 100 rpm. The length of the block (1) is twice its width (w). Assume, the coefficient of friction P is 0.35. Calculate: (1) the applied load (P) and the hinge-pin reaction (Rx ana Ry) for clockwise rotation of the drum; (2) the applied load and hinge-pin reaction for anticlockwise rotation of the drum; (3) the rate of heat generated during the braking action. (4) The dimensions of the block, if the intensity of pressure between the block and brake drum is 1 MPa. (5) Check whether the brake is self-locking.
In a wheel and differential axle type of lifting machine, a crank handle of 240 mm radius takes the place of the wheel and the diameters of the differential axle are 110 mm and 80 mm respectively. If an effort of 80 N is required at the handle to lift a load of 1.12 kN, find the velocity ratio, mechanical advantage and efficiency at this load.
