A Proton C a r of a mass, mp = 500 kg is traveling across a Sultan Iskandar bridge of a total length, l = 300.0 m and mass. 111:, = 8500 kg as shown in Figure 2. The sub-structure of the bridge is made to give support for the heavy superstructure above it by using two pillars and one pier. Given the pier exerts 50,000 N force to make the bridge remain in static equilibrium. Calculate forces exerted by supports pillar A and pillar B. 1?th A File: B
