Experimental Purposed
The purpose of this experiment is to understand the relationship between stress and strain and Young's modulus by measuring strain and calculating stress. Understand the principle of operation of the strain gage and the Wheatstone bridge circuit and use it to learn how to attach a strain gage to the specimen and how to connect the circuit so that the strain can be measured in the half bridge method.
Finally, use CATMAN S/W to measure the strain and learn how to identify the properties of the material. Through this process, knowledge that has only been learned theoretically can be reconfirmed through experiments, and engineering insights that can be applied to the field can be obtained.

Experimental Theory

1-1. Mechanical property
The properties that represent the behavior of a material when it is under load are called mechanical properties. there are strength, stiffness, toughness, ductility, hardness, elasticity, etc.
