Problem 7.10 Part A -5 kN/m, determine the internal normal force, shear force, and moment at point C in the double-overhang beam (Egure 1 Determine the internal mormal force Express your answer with the appropriate units Nc Value Units sty Answers Part B Determine the shear force Express your answer with the appropriate units. Vc-Value Units lly Answers fve Part C Determine the moment Figure 1 lof! Express your answer with the appropriate units. Mc= Value Units ty Answers Gve Up 5m-1.5m- 1.5 m1.5 mExplanation / Answer
the intensity of the traingular distributed loading at C can be computed using the similar triangle
Wc/3 = 5/4.5
Wc = 3.33 kN/m
moment at B in anti clockwise direction = 0
1/2*5*4.5*1.5 -1/2*5*1.5*1.5 -Ay*3 = 0
Ay = 3.75 N
sum of Fx = 0
Ax = 0
Fx = 0 Nc = 0
sum of Fy = 0 = 5 - 1/2 * 3.75*3 - Vc = 0
Vc = 5 x 10^-3
sum of Moment at C = 0
Mc + 1/2 * (3.33)*(3)*1 - 5(1.5) = 0
Mc = 2.5005 kN-m
