Given the radius of the solid shaft A-B is 40 mm and the shear modulus is 75 GPa, find the maximum shear stress in the shaft. Assume that point B is fixed, whereas point A is a flexible support modeled as Ta= ko, where k = 0.5 x 106 Nm/rad. 2 kN m 4 kN-m 600 mm 3 600 mm 600 mm Reference: Mechanics of Materials, Russell C.
