Course Outcomes

### Force Equilibrium

1(a) Apply Newton's Laws of force equilibrium to determine axial forces, shear forces, and bending moments in statically determinate beams, trusses, frames, arches, and cables.

### Virtual Work

2(a) Apply calculus and the principle of virtual work to determine displacements in statically determinate beams, trusses, and frames.

### Approximate and Plastic Analysis

3(e) Use appropriate assumptions to perform approximate analysis and plastic hinge analysis of statically indeterminate beams and frames.

### Influence Line Diagrams

4(e) Critically place live loads on beams, trusses, and frames using influence line diagrams.

### Symmetry, DOI's, and DOF's

5(e) Identify symmetry, antisymmetry, degrees of indeterminacy, and degrees of freedom in beams, trusses, and frames.

### Structural Terminology

6(n) Define basic structural engineering terminology.

### Flexibility Method

7(n) Analyze statically indeterminate beams, trusses, and frames by the flexibility method.

### Stiffness Method

8(n) Analyze beams, trusses, and frames by the stiffness method.
