Catalog description: Prerequisites: MATH 231, ENGR 212. Offered in fall and spring. Kinematics and kinetics of a
particle, system of particles, and rigid bodies. Energy and momentum methods. Engineering applications.
Prerequisites:
1. Knowledge of Newton's laws of motion for particles
2. Ability to draw free body diagrams.
3. Basic knowledge of calculus
4. Ability to sketch graphs of functions
Textbook: Vector Mechanics for Engineers: Dynamics, F.P. Beer and E.R. Johnston, McGraw-Hill, 7th edition, 2004.
Course goals:
1. Develop the ability to use Newton's laws for dynamic situations.
2. Develop the ability to select the correct approach in dynamics.
3. Develop the multi-step approach as the model of problem solving
Course outcomes: After completing the course, students will be able to:
1. Choose the methods (Newton’s laws, work energy, impulse momentum) to best solve a dynamics problem
2. Work with and convert between, X-Y, N-T, R- coordinate systems
3. Analyze the kinematics of the crank slider and four bar linkage for velocity and acceleration
4. Apply Newton’s laws to planar motion to obtain instantaneous acceleration of a body by drawing the appropriate
free body diagram, corresponding equations of motion, and solving the equations
5. Apply the work-energy method to planar motion problems involving translation and rotation
6. Apply impulse-momentum methods to planar motion problems involving translation and rotation
