Two concentric heavy steel springs support a load or 9100N as shown in the figure. The outer spring is made from a 30-mm diameter wire on a mean diameter of 220 mm and has 22 tuns. The inner spring consists of 30 turns made from 20-mm diameter wire on a mean diameter of 160 mm. Using G = 83 GPa, calculate the shearing stress developed in the two springs.
