A 75.0 kN truck is parked in the middle of a 20.0 m long bridge. How much force must each end of the bridge exert to support the truck?

**Physics**

P = F/A But there are two tires. So the weight will be supported by the two tires, thus two areas. So P=F/2A, solving this, A = F/2P A = 600/2*6.7*10^5
