Question:
Design a semi-elliptic leaf spring 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 of the spring is 1 m. The maximum force acting on the spring is 10 kN and the width of each leaf is 50 mm. The spring is initially pre-loaded in such a way that when the load is maximum, the stresses induced in all the leaves are equal to 350 N/mm2. The modulus of elasticity of the leaf material is 207000 N/mm2.
