The Gambrel truss shown supports one side of a bridge; an identical truss supports the other side. Floor beams carry vehicle loads to the truss joints. Using the Method of Joints, calculate the forces in the truss members when a truck having a mass of $3500kg$ is stopped in the middle of the bridge as shown. The centre of gravity of the truck is $1$ metre in front of the rear wheels.ay I please have a clear worksheet showing all the necessary diagrams of the joints, calculations and explanations if necessary. This will be very beneficial to my studies so please give it your best shot. ~Thank you for yout co$-$operation.
