A vertical close coiled helical spring must have a stiffness of 4,3 kN/m. The maximum shear stress of 130 MPa is induced by a load of 720 N. With the spring fully compressed, the vertical height over the coils is 250 mm. If G = 79 GPa, calculate:

3.1 the required wire diameter for the spring;

3.2 the mean coil diameter and the number of coils.
