A solid bar having a diameter 150 mm is to be replaced by a square tube having a cross-sectional dimension shown in the figure. A. Determine the required dimension "a" if the thickness is 10mm so that the maximum shear stress in the tube will not exceed the maximum shear stress in the solid bar. B. Determine the shear stress in the tube if it is subjected to a torque T = 12 kN.m. C. Determine the angle of twist in degrees of the tube if the length of the tube is 800mm and the shear modulus is 75GPa, T = 12 kN.m.
