(a)Describe, with a labelled diagram, how you would measure accurately the extension of such a wire under an applied load. (b) The graph below shows how the extension of a wire varies with the load applied to it. The wire used has a length of 3m and a diameter of 5 x 10^-4m  i. Calculate the tensile stress produced by a load of 50N. ii. Find the energy stored in the wire when the load is acting. iii. Calculate the reduction in gravitational PE of a 5kg mass used to provide the load. iv. Calculate Young's modulus for the metal of the wire.
