Course Description: Non-deformable, rigid body mechanics applied to structures that are at rest or move with constant velocity. Introduces modeling positions, forces, and moments within structural components as vectors; static equilibrium; free body diagrams; internal forces (shear/moment diagrams); centroids and centers of gravity; moments of inertia; and friction. Emphasis given to practical applications and how the subject applies in industry.

Student Learning Outcomes

Solve problems using several common unit systems.
Model physical quantities using scalars (e.g., masses) and vectors (e.g., positions; forces; moments) in two and three dimensions.
Identify and draw free-body diagrams for particle systems and rigid body structures.
Describe and model various types of loading (e.g., friction) and support conditions that act on structures.
Apply equations of equilibrium to resolve the loads in particle systems and rigid body structures.
Explain the difference between statically determinant and indeterminant structures.
Describe key assumptions in modeling trusses, space frames, etc. using beams, bars, rods, etc.
Utilize previous learning outcomes to perform analysis on structural components.
Calculate the internal loads (e.g., shear and moments), centroids, and moments of inertia of structural members and describe how these concepts apply to mechanics of materials.
Generate solutions to engineering statics problems in an organized, coherent manner so that the results may be understood by those outside of the engineering profession.
