Design a truss bridge. The bridge will support a road of mass 100 kg / m. A truck of mass 15,000 kg will drive across the bridge. The mass of the trusses are negligible compared to the road and the truck. Calculate the force in each of the trusses as the truck drives across the bridge at 5 m/s. Create a 2 - 3 page report of your work, and an interactive spreadsheet and animation showing how the forces in the trusses change as the truck drives across the bridge.
