A semi-elliptic spring used for automobile suspension, consists of two extra full-length leaves and eight graduated-length leaves, including the master leaf. The centre-to centre distance between the two eyes is 1 m. The leaves are made of steel 55Si2Mo90 (Syt = 1500 N/mm2and E = 207000 N/mm2) and the factor of safety is 2. The maximum spring load is 30 kN. The leaves are pre- stressed so as to equalize stresses in all leaves under maximum load. Determine the dimensions of the cross-section of the leaves and the deflection at the end of the spring.
