Explanation Given information: The vertical force Q is 50 lb The horizontal force P is 80 lb. The angle α between the force P and Q is 45 ° . Calculation: Apply the parallelogram law of addition and triangular rule. Follow the steps to draw the parallelogram law of addition. 1. From the head of magnitude of force 50 lb, draw a line, parallel to the magnitude of the force 80 lb. 2. From the head of magnitude of force 80 lb, draw a line parallel to the magnitude of the force 50 lb. 3. Join the above two lines at an intersection point to form the adjacent sides of a parallelogram. Draw the resultant force R at the intersection point as in Figure 1. Refer Figure 1. From the point of intersection, the two forces are laid off at a convenient scale, the parallelogram is drawn, and the diagonal represents the resultant force
