A close-coil helical spring is to have a stiffness of 1,000 N/m in compression, with a maximum load of 50 N and a maximum shearing stress of 125 N/mm². The solid length of the spring is 50 mm. Find the wire diameter, mean coil radius, and a number of coils. G= 54,000 N/mm². (Assume shear stress is produced only due to the torque produced in the wire due to axial loading).
