### Problem Statement The image presents a problem related to stress analysis. The tasks are as follows: a) Determine the principal stresses. b) Calculate the maximum in-plane shear stress. c) Specify the orientation of this stress element. ### Diagram Description The diagram on the right shows a rectangular stress element subjected to various stresses: - The element is oriented with its sides aligned along the x and y axes. - Normal stresses are applied as follows: - 80 MPa in compression along the negative x-direction. - 80 MPa in tension along the positive x-direction. - 25 MPa in tension along the negative y-direction. - Shear stresses are represented with arrows indicating the direction: - 50 MPa acting on the top and bottom faces with opposite directions. Points A and B on the diagram are labeled for reference. ### Analysis To solve this problem, follow these steps: 1. **Principal Stresses**: Compute using the stress transformation equations or Mohr's Circle. 2. **Maximum In-Plane Shear Stress**: Determine using the appropriate formula. 3. **Orientation of the Stress Element**: Find the angle at which the principal stresses occur for the given element. This information is critical for understanding the behavior of the material under the given loading conditions.
