Design a leaf spring to meet these requirements if infinite-life is desired.

1.A multileaf simply supported truck spring is to be designed for each rear wheel, using AISI 1095 steel ( , , ). The truck weight is 16 kN, with 65 percent of the weight on the rear wheels. The static midspan deflection is 100 mm and the maximum midspan deflection during operation is 200 mm. The loading may be considered to be released cyclic loading. The length of the spring between supports must be between 1.2 m and 1.6 m. It has been decided that a design factor of safety of should be used. Design a leaf spring to meet these requirements if infinite-life is desired.
