Manufacturing engineering-
A single strain gauge is mounted to measure the axial strain in a simple tensile member the recorded strain is 200 microstrain, what is the axial stress ?
a) If the member is of steel?
b) if the member is of aluminium ?
The modulus of elasticity of steel is 200 GPa and that of aluminium is 70 GPa
Hooke's law is used to correlate true stress and true strain in the plastic region of the stress/strain curve.
