Engineering Mechanics problem with solution. got to my playlist to get more specific topics. F2–4. The triangular plate is deformed into the shape shown by the dashed line. Determine the normal strain developed along edge BC and the average shear strain at corner A with respect to the x and y axes. F2–5. The square plate is deformed into the shape shown by the dashed line. Determine the average normal strain along diagonal AC and the shear strain of point E with respect to the x and y axes.
