#### ENGRMAE 30 Statics

**ENGRMAE 30 Statics (Credit Units: 4)** Addition and resolution of forces, distributed forces, equivalent system of forces centroids, first moments, moments and products on inertia, equilibrium of rigid bodies, trusses, beams, cables. Corequisite: Mathematics 2D. Prerequisite: Math 2D and Physics 7C. School of Engineering majors have first consideration for enrollment. Same as ENGR 30 and ENGRCEE 30. (Design units: 0)

1. Analyze and draw free body diagrams for single particles and rigid body systems. (EAC a)

2. Calculate centroids of areas and moments of inertia. (EAC a)

3. Establish equilibrium equations of particles/rigid bodies for solve for forces and support reactions. (EAC a)
