Course Objectives
- Critical Thinking
- Calculate the moment caused by a two- and three-dimensional force or system of forces acting on a rigid body.
- Use a free body diagram and the equilibrium equations to determine the reactions at the supports of two- and three-dimensional structures.
- Use free body diagrams and the equilibrium equations to analyze structures (e.g., trusses, frames, simple machines).
- Determine internal loading in a member at a specific point.
- Use the internal loading to determine the internal shear and moment along the length of a member and draw shear and bending moment diagrams.
- Solve equilibrium problems involving dry friction.
- Explain the concepts of static and kinetic friction.
- Quantitative Reasoning
- Apply vector algebra to resolve two- and three-dimensional force systems.
- Locate the centroids and center of mass of homogenous and non-homogenous areas, volumes, and masses. Use the centroid location techniques to analyze distributed loads.
