Prince George's Community College: EGR 2200: Engineering Mechanics

Course Description:

Principles of mechanics including points, bodies, and assemblies in static equilibrium. Areas examined will including trusses, frames, beams, cables, machines, point and distributed loading, and moments of inertia, scalar and vector analysis. More advance topics will include deformable bodies and stress, strain, torsion, shear, bending, and fracture. Introduction to kinetics, kinematics, and strength of materials.
See below for more details.
