2. Fasteners, such as nails, bolts, glue, or welds, are used to connect the composite parts of a "built-up" section. The shear force resisted by these fasteners is determined from the shear flow, q, or force per unit length that must be carried by the beam. The shear flow is q=VQ/1. Why is the statical moment of area Q based on the shaded portion of the section? Explain symbolically. Show diagrams. 3. The boards below are glued together to form an 1-section. Using only FBDs show how will you solve for the statical moment of area Q_top and Q_bott. Just show the sketches. No need to run numerical calculations.

Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a = 2.2 m, b = 4.4 m, c = 3 m, P = 16 kN, w = 34 kN/m, and Q = 26 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 1.40 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.
