Problem 1b. For the beam shown in the figure, draw the influence lines for: (a) Shear at point C; and (b) Moment at point C. The beam has a dead load due to self-weight of 0.8 KN/m. A concentrated moving load of 20 KN and a uniformly distributed moving load of 1.2 KN/m act on the beam. Determine the maximum negative shear possible at point C under these loads.
