5. Course Learning Objectives:
By completion of the course, students should be able to:

• Determine the components of a force in rectangular or nonrectangular coordinates.
• Determine the resultant of a system of forces.
• Draw complete and correct free-body diagrams and write the appropriate equilibrium equations from the free-body diagram.
• Determine the support reactions on a structure.
• Determine the connection forces in trusses and in general frame structures.
• Determine the internal reactions in a beam, draw correct shear-force and bending moment diagrams, and write equations for the shear-force and bending moment as functions of position along the beam.
• Analyze systems that include frictional forces.
• Locate the centroid of an area.
• Calculate the second moment of an area, calculate the principal second moments of an area.
