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. Solve FL using summation of moments from the other half of the section. Solve QG and QM using Method of Joints.arrow_forwardTandem drawing of wires and tubes is necessary because; Surface finish improves after every drawing stage OIt is not possible to reduce at one stage O Annealing is needed between stages Accuracy in dimensions is not possible otherwise Which of the following abrasive materials is most appropriate for grinding nonferrous metals?
