4) A set of individual strain gages are glued to a steel plate in the orientations shown. Upon loading, their readings indicate the following: Gage (a): 450 microstrain Gage (b): 2850 microstrain Gage (c): -675 microstrain (a) Find the normal strains along the x and y directions, and the in-plane shear strain ɛy. (b) Draw the strain element. Find the principle strains & maximum shear strain and how these orient themselves relative to the xy axis.
