The analysis of structures is best performed using a step-by-step process. You must begin by identifying the know quantities and the unknown variables. A Free Body Diagram is required in order to determine which equations of equilibrium will be used to solve for the unknowns. In the case of the Method of Joints, this process is repeated until the forces in all truss members are identified. Some shortcuts can be used if all the forces in the truss are not required.
Complete and submit the problems below:
- Clearly present
- The known data
- The unknowns
- The formulas needed, and
- Sketches, where applicable
- Use consistent units and proper prefixes (Do not switch or convert between USCS and SI)
- Round off final answers to proper degree of precision or accuracy (Use 3-4 significant digits)
- ID your final answer with proper unit
