Two steel springs arranged in series supports a load P. The upper spring has 12 turns of 20-mm-diameter wire on a mean radius of 100 mm. The lower spring consists of 10 turns of 25-mmdiameter wire on a mean radius of 75 mm. If the maximum shearing stress in either spring must not exceed 300 MPa, compute the maximum value of P and the total elongation of the assembly. Use approximation formula and G=83 GPa. Compute the equivalent spring constant by dividing the load by the total elongation.
