For the horizontal beam of length 2m with applied loads as shown in the figure, evaluate the resultant moment about the point A (taking counter-clockwise as being positive). Assume negligible thickness of the beam. Give your answer in Nm. a = 21.0 N, b = 17.5 N, c = 1.1 m bN A 0.5 m a N cm 45 5 Nm 0.5 m a N
