A circular steel tube of length L= 1.0 m is loaded in torsion by torques T (see figure).
(a) If the inner radius of the tube is r1= 45 mm and the measured angle of twist between the ends is 0.5°, what is the shear strain & Y1 (in radians) at the inner surface?
(b) If the maximum allowable shear strain is 0.0004 rad and the angle of twist is to be kept at 0.45°by adjusting the torque T, what is the maximum permissible outer radius (r2)max?
