Atest specimen is10 mm wide, 2 mm thick, and 150 mm long, and is subjected to an axial force of 200 n. the fibers are oriented at 100 with respect to the loading axis. a) compute the in-plane strain vector in the material coordinates (1, 2). b) compute the in-plane strain vector in the global coordinates (x, y). c) compute the out-of-plane strain vector {yz xz } in the global coordinates.
