Two steel springs are arranged in series. They support a load P. The upper spring has 12 turns of 25 mm diameter wire on a mean radius of 100 mm. The lower spring consists of 10 turns of 20 mm diamter wire on a mean radius of 75 mm. If th maximum shearing stress in either spring must not exceed 200 MPa and G = 83 GPa, determine the maximum possible value of P (KN). Assume the springs are light springs.
