1. Identify and eliminate all of the zero force members in the Pratt truss shown. 2. Redraw the truss with only non-zero force members (linear pairs of members joined by a pin can be assumed to be a single member) 3. Then, find the internal forces in all members on the left side of (and including) the centerline JD. Note that the truss, loading, and supports are symmetrical, thus the internal forces are as well Please provide all written work and FBD to learn from, thank you!

Use 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. W C b Answer: Vmax= Mmax B kN kN-m С
