A composite spring consists of two close-coil helical springs connected in series. Each spring has 14 coils at a mean diameter of 20 mm. The stiffness of the composite spring is 800 N/m. If the wire diameter of one spring is 2.5 mm, find the wire diameter of the other. What will be the maximum load which can be carried by the composite spring and the Take G=78 GPa. corresponding deflection for maximum shear stress of 150 MPa?
