Objectives
- Calculate a structure's support reactions.
- Judge the most efficient method to determine a structure's internal forces and moments.
- specific cut → V&M values
- arbitrary cut → V&M equations → V&M graphs
- integration → V&M equations → V&M graphs
- area → V&M graphs → V&M equations
- superposition → V&M graphs
- Calculate shear-force and bending-moment values at a particular point in the structure.
- Derive the shear-force and bending-moment equations within a region of the structure.
- Draw the shear-force and bending-moment graphs for the entire structure.
