Question

A semi-elliptical spring of length 500 mm, thickness 10 mm, and 40 mm broad is subjected to a load of 5 kN and get straightened. If the stress in spring should not cross 250 MPa, then calculate the number of plates, the initial radius of curvature, and central deflection. Take E as 200 GPa​
