THANK YOU IN ADVANCE! Solve the forces in PQ, FL, QG, and QM. Hint: Identify all zero-force members and remove them from the structure. In the summation of moments, look for a point where member forces at the supports converge so that their moment arm is zero. From here you will be able to solve PQ.
