A composite spring has two closed coiled springs connected in series, each spring has 12 coils at a mean diameter of 25mm. Find the wire diameter for one if the other is of 2.5mm diameter and the stiffness of the composite spring is 700N/m. Estimate the greatest load that can be carried by the composite spring, and the corresponding extension, for a maximum shear stress of 180MPa. Take G=80GPa.
