BCN 3251C, Structure Force System Practice Name (print): 3. A laborer is hoisting a weight, W=200 #, by pulling on a rope as shown. Determine the force F required to hold the weight in the position shown if the resultant of F and W acts along the axis of the bottom. F 30 W-200 2. Three members of a truss frame into a steel gusset plate as shown. All forces are concurrent at point O. Determine the resultant of the three forces that must be carried by the gusset plate. F =10k 451 2=12k F3=18k X - 0 = tan (+) = 45
