INDIAN INSTITUTE OF TECHNOLOGY, BOMBAY ME 202 – S1 - SOLID MECHANICS Tutorial Sheet # 1 Q1. Consider a closed coiled linear spring as shown in figure (a) below. Find the distribution of shear stress in the cross-section of the coiled wire. The material is linear elastic with a shear modulus G. Q2. The system of shafts and gears shown in figure (b) is assembled, it is required for the gears to mesh, the 75 mm diameter gear must be held stationary and the 125 mm diameter gear rotated through 30. Calculate the maximum shear stresses in the two shafts after assembly but before external torque is applied. The shear modulus is 80 GPa.
