Specific Goals for the Course
1. All Students

B. Be able to mathematically write and solve simple mathematical relationships that pertain to a physical situation including:
- Be able to write force and moment vectors and manipulate them.
- Be able to write force reactions in x, y, and z directions and solve them simultaneously.
- Perform 2-D force rotations to a new coordinate axis.
- Calculate bending, torsional, transverse shear, and tension stresses and deflections for a variety of loading conditions.
- Determine if a material, with a known yield strength, will yield given the principal stresses.
C. Be able to interpret the effects of loading on a beam including:
- Draw the shear and moment diagrams for a loaded beam.
- Be able to draw the shear and moment diagrams for 3 and 4 point flexure and discuss differences during mechanical testing.
D. Demonstrate the use of mathematical software (like Mathcad) to solve a design problem.
2. Most Students
A. Be able to design a component that is part of a larger system including:
- Be able evaluate which type of stress (bearing, shear, bending, tension) will cause failure for a member subject to stresses from forces and moments.
- Design the cross-section of a beam to meet certain design criteria.
B. Be able to analyze a complex loading state including:
