The figure shows a uniform AB shape, 3.0m long, having the point of support 1.0m away from edge A. The weight and beam is 200N. 1.0 m 2.0m a Copy the figure and mark the center of mass of the beam. b Draw the arrows representing the following forces: the weight of the beam, the contact force acting on the beam at the point of support. c An Fe force is exerted vertically downwards on the beam (at end A). How much must this force be, that the beam of life in balance? d When this force is exerted, what is the contact force at the point of support of the beam? [1] [2] [5] [3]
