The main objective of this experiment is to recapture stress, strain and fully understand the relationship between them under the elastic zone of the materials using Hook’s law and use stress transformation equations when a load is applied in arbitrary direction. The other motivation is to verify the measured value of the strain and stress using transformation equations that are found by geometric manipulation. To accomplish these tasks we will load a structure with a constant load at a measured or specific location from the fixed point and measure the strain that it produces. Since most materials fail under 3500μ strain, the conventional measuring devices like scales that have low resolution (i.e. it can only measure 1/32 of an inch within 1/64) will not be used to measure the change in length. So to achieve this task we will be using strain gages that have high resolution and are able to measure small change in length up to ± 1μm.
