UTM , test specimen, divider, vernier caliper, scale.
Procedure:
Prepare the test specimen that is steel bar and find its diameter at tree different places and find its man value.
Mark two points 8" a part of 2 ft long steel bar.
Insert the bar in jaws for gripping the steel bar and select suitable bar on UTM. Place the steel bar and fix it.
Start t machine and start applying load.
There will be gradual increase in length which will be directly proportional to applied load.
During this load application measure change in length at different load, till the steel bar breaks.
Find the stress and strain at those points and investigate the law by drawing the graph between stress and strain
