Comprehensive analysis of basic principles of statics, including vector and scalar treatment of multi-dimensional force systems. Studies include sectional forces in beams, cables and frames. Shear and moment diagrams that are developed using methods of joints and sections are incorporated in these studies. Free body diagrams are used to calculate forces on frames, cables and machines. A process is developed for evaluating static determinacy of multiple force systems. Frictional forces on static systems are analyzed. Other topics include an investigation of static equilibrium, resultant forces and equivalent force systems. Fall only. Prerequisite: PHY 132.
