Two steel springs with plain ends are arranged in series and supports a load. The upper spring has 13 turns of 28-mm-diameter wire on a mean diameter of 200 mm. The lower spring consists of 9 turns of 21-mm diameter wire on a mean diameter of 150 mm. The maximum shearing stress in either spring must not exceed 240 MPa. Use G = 83 GPa. Calculate the maximum allowable load in the spring assembly in N.
