I am not reallyunderstanding what this problem wants with the wording, coud you help me clarify that please? Thank you so much!! Problem 18.2An engineer wants to measure strain at a key point on a prototype part in order to estimate the stress that ispresent. Suppose that a point on the surface of a part is noted to be in biaxial stress (no stress normal to thepart surface) and strains are measured to be.x = -500µ, &y = -450µ, and Yxy = -250µ. (note that u is theprefix for "micro")Determine the state of stress in the x-y orientation. Furthermore, determine the principal stresses andabsolute maximum shear stress present in the material. Determine the planes on which these stresses actand show them (along with other relevant stresses at that orientation) on a sketch.The material has properties, E = 15000 ksi and v= 0.34

Here we have, εx = -500×10-6εy = -450×10-6γxy= -250×10-6E =15000 Ksiν =0.34
