A rigid plate of negligible mass rests on a central spring which is 20 mnm higher than the symmetrically located outer springs. Each of the outer springs consists of 18 turns of 10 mm wire on a mean diameter of 100 mm. The central spring has 24 turns of 20 mm wire on a mean diameter of 150 mm. If a load P = 5 kN is now applied to the plate, use G = 83,000 MPa. Determine the load carried by the central spring, in kN. Determine the shearing stress of the central spring, in MPa. Determine the shearing stress of the outer spring, in MPa.
