- Mohr's circle is shown for a point in a physical object that is subjected to plane stress. Each grid square is 880 psi in size. (a) Determine the stresses Ox, Øy, and the magnitude of Txy 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). C X Ø C y (1 bUse the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a = 3.2 m, b = 6.4 m, c = 4.3 m, P = 21 kN, w = 45 kN/m, and Q = 18 kN. Label all significant points on each diagram and identify the maximum shear force and bending moment along with their respective locations. Additionally: (a) Determine V and M in the beam at a point located 0.65 m to the right of B. (b) Determine V and M in the beam at a point located 1.20 m to the left of C. Note that answers may be positive or negative. Here, "maximum" refers to the largest magnitude value, but you should enter your shear force and bending moment with the correct sign, using the sign convention presented in Section 7.2 of the textbook. If the magnitudes of the largest positive and largest negative values are the same, enter a positive number.
