A steel plate with modulus of elasticity E = 30 × 106 psi and Poisson's ratio = 0.30 is loaded in biaxial stress by normal stresses σx and σy (see figure). A strain gage is bonded to the plate at an angle = 30°.
If the stress σx is 18,000 psi and the strain measured by the gage is e 407 × 10-6, what is the maximum inplane shear stress (tmax)xy and shear strain (Ymax)xy? What is the maximum shear strain (Ymax)xz in the xz plane? What is the maximum shear strain (Ymax)yz in the yz plane?
