Two concentric spring close-coiled helical springsarranged one within the other, control the operation of a valve.The particulars of the outer spring are: 12 coils, 25 mm mean coildiameter, wire diameter 3 mm and initial compression when valve isclosed = 5 mm. The initial compression of the inner spring is 11 mmand a total load of 150 N is required to open the valve 10 mm.Calculate the stiffness of each spring and the number of coils onthe inner spring if its wire diameter is 2 mm and the mean coildiameter is 15 mm. What will the stress in each spring be? Take Gfor both springs as 81.5 GPa.
