Document Summary

Transfer of a force to parallel position. Simple truss & solutions of simple truss. Centroid of plane, curve, area ,volume & composite bodies. Plane motion of rigid bodies, velocity & acceleration under translation & rotational motion, relative velocity, projectile motion. There are many ways in which forces can be manipulated. It is often easier to work with a large, complicated system of forces by reducing it to an ever decreasing number of smaller problems. This is called the resolution of forces or force systems. This is one way to simplify what may otherwise seem to be an impossible system of forces acting on a body. Certain systems of forces are easier to resolve than others. Coplanar force systems have all the forces acting in in one plane. They may be concurrent, parallel, non-concurrent or non- parallel. All of these systems can be resolved by using graphic statics or algebra.
