QUESTION 2 An element in plane stress is subjected to stresses; Ox ,Oy, and Txy (FIGURE 2). Using Analytic method, determine the stresses acting on an element oriented at an angle 0. (Note: The angle 0 is positive when counter clockwise and negative when clockwise) i. Normal Stress (ox', oy ') ii. Normal Shear Stress (Txy') iii. Shear Stress Maximum (t max ) iv Show the stresses on a sketch of an element oriented at the angle A

Mohr’s circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 600 psi in size. (a) Determine the stresses σx, σy, and the magnitude of τxy and show them on a stress element. (b) Determine the principal stresses and the magnitude of the maximum in-plane shear stress acting at the point and show these stresses on an appropriate sketch (e.g., see Figure 12.15 or Figure 12.16).
