A closed coil vertical spring-loaded valve is required for a compressed air receiver. The valve is to start opening at a pressure of 1 MPa and must be fully open with a lift of 4 mm at a pressure of 1.2 MPa. The diameter of the port is 25 mm. Assume the allowable shear stress in steel as 480 MPa and shear modulus as 80 GPa. Design a suitable close coiled round section helical spring having squared ground ends. Also specify initial compression and free length of the spring

A semi-elliptic spring used for automobile suspension, consists of twoextra full-length leaves and eight graduated-length leaves, including themaster leaf. The centre-to-centre distance between the two eyes is 1 m.The leaves are made of steel 55Si2Mo90 (S = 1500 N/mm yt2 andE = 207 000 N/mm2) and the factor of safety is 2. The maximum springload is 30 kN. The leaves are pre-stressed so as to equalize stresses in allleaves under maximum load.
