A bridge of length 50.0 m and mass 8.10 x 10 kg is supported on a smooth pier at each end as shown in the figure below. A truck of mass 2.80 x 10² kg is located 15.0 m from one end. What are the forces on the bridge at the points of support? 15.0 m normal force at point A normal force at point B Need Help? 50.0 m- 4512.00 X The bridge is in static equilibrium so the net torque must be zero. N 616910 If the truck is closer to point A does it make sense that the force on 8 is greater? N Master
