A damper square mat is supporting a dead load weight of 8 kN. Helical springs will be used to support the load located at all corners with shearing stress of 120.6 Mpa at 20 turns. The spring has a deformation of 98.7 mm with a mean radius of 80 mm. Design the minimum diameter of the wire to support a load. Use G = 83 Gpa. 8 kN
