Calculate the maximum stress due to Bending in a steel strip of 30 mm thick and 60 mm wide is bent around a circular drum of 3.6 m diameter .

Calculate the maximum stress due to Bending in a steel strip of 30 mm thick and 60 mm wide is bent around a circular drum of 3.6 m diameter . Correct Answer Take Young’s modulus = 200kN/m2

Thickness of steel strip = 30 mm; b = 60 mm; d = 3.6m R = 3.6/2 = 1.8 m E = 200 kN/m2 y = 30/2 = 15 mm E/R = f/y ; f = 200000×15/1800 = 1666.67 N/mm2.

A haulage rope winds on a drum of radius 500 mm, the free end being attached to a truck. The truck has a mass of 500 kg and is initially at rest. The drum is equivalent to a mass of 1250 kg with radius of gyration 450 mm. The rim speed of the drum is 0.75 m/s before the rope tightens. By considering the change in linear momentum of the truck and in the angular momentum of the drum, find the speed of the truck when the motion becomes steady.
