1.A load P is supported by two concentric steel springs arranged as shown. The inner spring consists of 30 turns of 20 mm. diameter wire on a mean diameter of 150 mm. The outer spring has 20 turns of 30 mm. wire on a mean diameter of 200 mm. Compute the maximum load and minimum load in the inner spring that will not exceed a shearing stress of 140 MPa in either spring. Use G = 83 GPa.
