This week we are going to use strain gages and flexure specimens to measure Young's modulus and Poisson's ratio. Your beam will be made from either aluminum or magnesium and have a biaxial strain rosette on either the top or bottom surface. We will assume that the flexure stress formula σ = My/I and the one-dimensional Hooke's law are valid. |
