Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. Answers: R= i 230 N M = i 320 N d = i Single resultant force. 230 N Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. 770 mm 770 mm 770 mm N N-m mm

Graphical Methods

The graphical method is a method of solving equations involving more than one variable using the Cartesian coordinate system. In civil engineering, the use of the graphical method is limited to the problems involving two variables. The graphical method has a great impact in solving the questions regarding engineering mechanics.
