Task $1$: Reaction forcesDetermine the reactions forces at the ends of your truss as a function of the dead and live loads. You may assume that the self$-$weight of the bridge is negligible. Compare answers with your group membersTask $2$: Internal forcesUse Method of Joints to determine the force in each member as a function of the dead and live loads. Use Method of Sections to check your calculation based on Method of Joints for at least one cut. The purpose here is to make sure that you know how to use this method.
