Find the maximum moment of the given load train at point n on the beam given in the figure? (Single load and distributed load train move on the beam. (a=9 m between n-A, b=3 m between n-B)
From the frame loaded as shown. Solve the following Find: Reaction at column BMoment at column B
For the beam shown, the magnitude of the distributed load is wo = 10.6 kN/m and the beam lengths are a = 6.3 m and b = 18.9 m. (a) derive equations for the shear force V and the bending moment M for any location in the beam. Place the origin at point A. (b) use the derived functions to plot the shear-force and bending-moment diagrams for the beam. Use your diagrams to determine the maximum shear force and the maximum bending moment. 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. Wo В a
