I am a teacher and need help creating exam problems. Please recommend more incorrect answers to the following problem but do not explain your logic. At a point in a body subjected to plane strain, the strains are εx = 280 με, εy = 80 με, and γxy = 500 μrad. Determine the magnitude of the maximum in-plane shear strain at the point.

I am a teacher and need help creating exam problems. Please recommend more incorrect answers to the following problem but do not explain your logic. A silicone rubber [E = 3.50 MPa, G = 1.20 MPa] wristband has an initial length of 101 mm and a width of 12 mm.
