A steel strip is to be bent round a drum of radius 1 m. What is the maximum thickness of a strip that can be bent in this way if the stress in it is not to exceed 100 MPa? The steel has a modulus of elasticity of 210 GPa. 7 A steel strip of thickness 5 mm is coiled on a drum of 1.5 m diameter. Calculate the maximum stress produced by the coiling. The modulus of elasticity is 210 GPa.
