M1 - moments, The plank is modelled as a uniform rod ps of length 2.4 m and mass 20 kg. the legs at q and r are 0.4 m from each end of the plank, as shown in figure 1. two pupils, arthur and beatrice, sit on the plank. arthur has mass 60 kg and sits at the middle of the plank and beatrice has mass 40 kg and sits at the end p. the plank remains horizontal and. Moments - maths genie, A uniform plank ab has weight 120 n and length 3 m. the plank rests horizontally in equilibrium on two smooth supports c and d, where ac = 1 m and cd = x m, as shown in figure 2. the reaction of the support on the plank at d has magnitude 80 n. modelling the plank as a rod, (a) show that x = 0.75. (3) a rock is now placed at b and the plank is.
