Young Modulus of a Metal Rod By an Interference Method.
Young Modulus of a Metal Rod By an Interference Method The experimental rod carries 2 metal plates at different points. These metal plates support a glass plate and a lens. One is on the top of the other adjusted by. 3 springs and screws. On applying a load the rod bends slightly, increasing the distance between the place and the lens. Newton's rings are observed before applying the load. As 'the end is applied gradually the rings run into the centre, disappearing one at a time. Complete with microscope tube but without weights.
