The strength of Earth's gravity at ground level = 9, point, 8, N, k, g, to the power minus 1 ,9.8Nkg−1. 1 tonne = 1000, k, g,1000kg. Where forces are asked for, ensure that the direction is in the answer (e.g. up/down). Assume that the mass is evenly distributed in the rulers, poles, planks, bridge spans mentioned in the questions. A 200, m,200m bridge span is supported at both ends. The span has a mass of 100, t, o, n, n, e, s,100tonnes. A 30, t, o, n, n, e,30tonne bus is 50, m,50m from one end of the span. Calculate the supporting force holding the bridge up at the end nearer the bus. Please give your answer to 2 significant figures.
