Two steel springs arranged as shown support a load P. The left spring consists of 12 turns of 20-mm diameter wire on a mean diameter of 300 mm. The right spring has 10 turns of 16-mm diameter wire on a mean diameter of 200 mm. Calculate the maximum value of P and the total elongation if the allowable shearing stress is 200 MPa.
