3.34 Replace the two belt tensions by an equivalent force-couple system at A.



















3.36 Three forces act as shown on a traffic-signal pole. Determine (a) the equivalent force-couple system at A (b) the resultant of the system and the point intersection of its line of action with the pole.










3.38 An angle bracket is subjected to the system of forces shown. Find the resultant of the system and the point intersection of its line of action with (a) line AB, (b) line BC .







3.40 Two cables exert forces of 18 kips each on a truss of weight W=40 kips . Find the resultant force acting on the truss and the point intersection of its line of action with the line AB .
