Elements and Performance Criteria
- Determine the resultant and equilibrant of systems of coplanar forces
- Determine nominal sizes for a simple horizontal beam subject to a combination of uniform and point loading
- Support reactions for a simply supported horizontal beam using the equations of equilibrium and including the moment effect of a couple are calculated.
- The possible types of failure that need to be considered are determined.
- Shear force and bending moment diagrams are drawn.
- Bending stress is determined.
- Calculations are completed to determine the nominal size for the beam.
- Factors of safety are applied to finalise nominal size of beam.
