The ends of a uniform wire of cross-sectional
area 10 *m and negligible mass are attached
to fixed points A and B which are 1 m apart in
the same horizontal plane. The wire is initially
straight and unstretched. A mass of 0.5 kg is
attached to the mid-point of the wire and
hangs in equilibrium with the mid-point at a
distance 10 mm below AB. Calculate the value
of Young's modulus for the wire. [O & C]
