A material element in plane stress is subjected to the stresses indicated in Figure 1. (a) Determine the stresses acting on an element that is inclined at a 45 counterclockwise angle relative to the original element as shown in Figure 2. (b) Determine the principal stresses and show the results on a sketch of a properly oriented element. You must indicate the orientation of this element relative to the original. (c) Determine the maximum in-plane shear stress and show the stress state at that orientation on a sketch of a properly oriented element. 40 MPa 50 MPa 10 MPa 145 - Figure 1 Figure 2 A material element in plane stress is subjected to the stresses indicated in Figure 1.
