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

• Determine the support reactions on and the pin forces in a general frame structure.
• Determine the internal reactions in a beam including: drawing complete and correct shear force and bending moment diagrams, and writing equations for the shear force and bending moment as functions of position along the beam.
• Calculate the stresses and strains associated with axial loads, torsional loads, bending loads, buckling loads, and pressurized circular cylinders both individually and in combination.
• Determine and illustrate principal stresses, maximum shearing stresses, and the stresses acting on any plane within a structural element.
• Determine and illustrate the deflections and rotations for axial loading, torsional loading, and bending.
• Calculate the velocity and acceleration of a particle in rectangular coordinates, in polar coordinates, in normal/tangential coordinates.
• Relate the velocity and acceleration of points in a rigid body using the relative motion approach.
• Solve particle kinetics problems using Newton’s second law, using work-energy methods, or using impulse-momentum methods.
• Solve rigid body planar motion problems using Euler’s equations, using work-energy methods, using impulse-momentum methods.
• Each class period will have specific learning outcomes that, collectively over the semester, will accomplish the course learning objectives.

Engineering Topics: 4 credits

9. Relationship of Course to Program Learning Outcomes and Program Educational Objectives
This course is designed for those engineering students whose curricula would otherwise include a dearth of required mechanics courses. It attempts to equip these students with a basic understanding of mechanics. Generally, the course develops student abilities in the application of fundamental principles of physics to the solution of engineering problems.

Specifically, this course provides moderate to considerable opportunity for students to:

• Apply a basic knowledge of mathematics and/or science to fundamental engineering mechanics problems (considerable)
• Apply knowledge of engineering to fundamental engineering mechanics problems (considerable)
• Identify and formulate fundamental engineering mechanics problems (considerable)
• Solve engineering problems (considerable)
• Analyze and evaluate structural elements (moderate)
• Develop the ability to engage in life-long learning (moderate)
