Engineering Dynamics

Learn Newton's second law, F equals ma, and solve dynamics using free body diagrams in x, y, and tangential coordinates.

Explore how work energy concepts apply to braking scenarios and roller coaster loops, linking friction, kinetic energy, and potential energy to predict stopping distances and loop speeds.

Explore relative velocity analysis for rigid body motion, using graphical and analytical methods to relate B to A and solve a bar-and-rollers problem for angular velocity.

Explore relative velocity analysis in engineering dynamics using graphical, analytical method, cross products, and the method of instant center to determine velocity relationships in planar mechanisms.

Perform relative acceleration analysis by decomposing a_B into a_A plus normal toward the center and tangential perpendicular to the bar, then determine omega and alpha via velocity analysis.

Apply relative acceleration analysis using the acceleration polygon to determine the acceleration of a mechanism's link C, integrating velocity relationships, normal and tangential components, and instant center considerations.

Apply relative acceleration analysis on a rotating link with a sliding point, deriving omega and alpha while accounting for Coriolis effects and velocity decomposition.

Use work-energy for rigid bodies to solve velocities with kinetic, potential, and spring energies; relate work to force along displacement and moment to angle, covering translation, rotation, or general motion.

Explore impulse momentum for rigid body systems, using linear and angular momentum, impulse, and angular impulse to solve collision problems and time‑dependent forces, with moment of inertia and contact points.

Apply impulse momentum analysis to rigid body systems, solving gear rack dynamics and a sign leg impact using moments, inertia, and energy methods, and compare approaches.
