statics

By possessing an understanding of Newton's Laws, following these three laws of graphical solutions, and understanding vector algebra you can solve most engineering static problems. Systems of Force Systems of force acting on objects in equilibrium can be classified as either concurrent or nonconcurrent and as either coplanar or noncoplanar. This gives us four general categories of systems. The first category, concurrent-coplanar forces occur when the lines of action of all forces lie in the …

…find the resultant of these forces it is best to resolve each force into components along three axes that make angles of 90 degrees with each other. Nonconcurrent-noncoplanar forces are when the lines of action of all forces do not pass through a common point and the forces do not all lie in the same plane. Stress When a restrained body is subject to external forces, there is a tendency for the shape of the body
