1) A straight hollow shaft is fixed at one end and free at the other end. The shaft is made of aluminium. Young's modulus of aluminium is 68000MPA and shear modulus of aluminium is 27000MPA. A torque To is applied to the shaft at its free end. Inner diameter of the hollow shaft is 80mm and its outer diameter is 100mm and length of the shaft is 2.50m. A) Calculate the value of the torque To that induces an angle of twist of 2.0°. B) What is the angle of twist when the sam torque To is acting at the free end of a solid cylindrical shaft of the same length and the same cross- sectional area. e
