Young Modulus of a Metal Rod By an Interference Method- Engineering Lab Training Systems.
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.
