Fig. 2 Exercise 3 (40 points) At a point in a structural member, on a plane 25o counterclockwise from the vertical plane through the point, the normal stress is 10 ksi. The normal stress on a plane 65o clockwise from the vertical plane through the point, is -20 ksi. The shear stress on a plane 55o counterclockwise from the vertical plane through the point is 10√3 ksi. (a) Show, on two separate sketches, the stresses for elements oriented at 25o and 55o. (b) Show, on two separate sketches, the principal and maximum shearing stresses at the point. (c) Draw Mohr's circle including all results from (a) and (b). ...
