A metal wire of length L1 and area of cross-section A is attached to a rigid support. Another metal wire of length L2 and of the same cross-sectional area is attached to the free end of the first wire. A body of mass M is then suspended from the free end of the second wire. If Y1 and Y2 are Young’s modules of the wires respectively, the effective force constant of the system of two wires is:
