ES 207 - Statics

Credit Hours: 3

Composition and resolution of forces, equivalent force systems, equilibrium of particles, and rigid bodies in two and three dimensions. Centroids and centers of gravity, analysis of simple structures, internal forces, friction, moments, and products of inertia in two dimensions. The unit vector approach is used.
