Course Description: Non-deformable, rigid body mechanics applied to structures that are accelerating. Expands on ENGR& 214 by introducing linear and angular velocity and acceleration of structural components as vectors. Geometric aspects of two- and three-dimensional motion for particles and structures treated using kinematics. Forces that cause this motion treated using kinetics and three different relationships: Newton’s Second Law of Motion; Work/Energy; and Impulse/Momentum. 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., velocities; accelerations; linear and angular momentum) in two and three dimensions.
Describe the difference between kinematics and kinetics.
Analyze the two- and three-dimensional rectilinear and curvilinear motion of particle systems using kinematics.
Calculate the forces that generate motion within particle systems using three different relationships: Newton’s Second Law of Motion; Work/Energy; and Impulse/Momentum.
Analyze the two-dimensional (planar) motion of rigid bodies and structural components (e.g., mechanisms) using kinematics.
Calculate the forces that generate motion within structural components using three different relationships: Newton’s Second Law of Motion; Work/Energy; and Impulse/Momentum.
Generate solutions to engineering dynamics problems in an organized, coherent manner so that the results may be understood by those outside of the engineering profession.
