Extracted text: 2. The allowable shear stress in the shaft is 70 MPa and the allowable angle of twist of end A relative to end D is 0.01 rad. What is the required minimum diameter d of the shaft if it has a solid cross section? The shear modulus of elasticity of the shaft is 80 GPa. 900 N · m 2000 N · m 400 N · m 700 N m A В 2 m 2 m D 2 m
