Y by bending of a bar technique is a simple and easy technique to determine Young’s modulus of Material such as Cu,Al,Fe, Stainless Steel,Wood etc. This technique require Traveling microscope, metal bar, two knife edges,weights etc. This technique can easily and accurately record the change in the dimensions of a bar under the load and measure depression at certain load by Traveling microscope. It has wide application in science and engineering. It is found that values of Young’ modulus obtained by using Y by bending of bar in close agreement with standard values of Y of material. The young modulus of iron was found highest 14.2128x1011 dyne/cm2 by Y by bending method.
