Reduction of a System of Coplanar Forces to One Force and One Couple. Resultant of a System of Coplanar Forces

Reduction of a System of Coplanar Forces to One Force and One Couple. Resultant of a System of Coplanar Forces:






















3.30 For the truss and loading shown, determine the resultant of the loads and the distance from point A to its line of action.


















3.32 Three horizontal forces are applied as shown to a machine arm. Determine the resultant of the loads and the point where its line of action intersects AD if the magnitude of P is (a) P = 50 lb, (b) P = 500 lb, (c) P = 350 lb.
