A uniform beam AB has a weight of 80 N and a length of x meters. The beam rests horizontally on two supports at points A and C, where AC = 2 m, as shown in Figure 2. A load of weight 20 N is placed at point B, and the beam remains in equilibrium. Given that the reaction on point C is 90 N. A 2m x m Figure 2 i) Find the reaction on A and the length of the beam, x. B ii) The support at A is now moved to a point D on the beam and the beam remains in equilibrium. The reaction at point C is three times the reaction at D. Find the distance AD.
