The 50 mm diameter rod has a stress strain diagram as shown. Knowing that the angle of twist is 2.5 degrees in a 725 mm length, determine a. the magnitude of the torque applied to the shaft. b. the shear strain in the shaft

The grain of a wooden member forms an angle of 15° with the vertical. For the state of stress shown, determine (a) the in-plane shearing stress parallel to the grain, (b) the normal stress perpendicu-lar to the grain.

The design specifications for the steel shaft AB require that the shaft acquire a strainenergy of 34 N.m as the 2.8 kN.m torque is applied. Using G = 72 GPa, determine(i) the largest inside diameter of the shaft that can be used,(ii) the corresponding maximum shearing stress in the shaft.

The aluminum rod AB (G= 27 GPa) is bonded to the brass rod BD(G= 39 GPa). Knowing that portion CD of the brass rod is hollow and has an inner diameter of 40 mm, determine the angle of twist at A.
