A bridge of length 50.0 m and mass 8.20 104 kg is supported on a smooth pier at each end as shown in the figure below. A truck of mass 3.10 104 kg is located 15.0 m from one end. What are the forces on the bridge at the points of support? A truck drives left to right across a 50.0 m bridge supported by a smooth pier at each end. The left end of the bridge is at point A and the right end of the bridge is at point B. The truck is 15.0 m to the right of point A.

a) normal force at point A N

b) normal force at point B N
