# ENGRCEE 30 Statics (2014-2015)

#### ENGRCEE 30 Statics

**ENGRCEE 30 Statics (Credit Units: 4)** Addition and resolution of forces, distributed forces, equivalent systems 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 ENGRMAE 30. (Design units: 0)

1. Analyze and draw free body diagrams for single particles and rigid body systems.

2. Calculate centroids of areas and moments of inertia.

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

4. Apply the theory and methods to analyze simple trusses.

5. Compute internal forces in cables/beams.

6. Formulate statics problems for simple structural beams.

Newtonian mechanics, kinematics, and dynamics of motion. Differential and integral calculus of real-valued functions of several real variables, including applications.
