Course Description

This course is an introduction to kinematics and kinetics of particles and rigid bodies. Vector analysis and calculus are used extensively as the tool to describe the motion of the systems and also to study the kinetics of particles and rigid bodies. Topics involved are the geometry of the motion (kinematics), and the methods of analysis, which include second law of motion, work-energy and momentum-impulse methods as applied to particles, system of particles and the rigid bodies. The mechanical vibration of particles and the rigid bodies are also studied in detail. It includes free and forced vibration, with and without damping. PREREQUISITE: ENGR A280. Transfer Credit: CSU; UC. C-ID: ENGR 230.C-ID: ENGR 230.

Course Level Student Learning Outcome(s)

1. Upon completion of the course the student will be able to derive and apply the laws of kinematics to analyze the motion of a partical, system of particles, and a rigid body in translation, rotation and general motion in 2-D and 3-D, and analyze the system in plane motion relative to a rotating frame of reference.
2. Upon completion of the course the student will be able to Newton’s second law to analyze a particle in rectilinear or curvilinear motion and a rigid body in plane motion under the influence of forces and moments.
3. Upon completion of the course the student will be able to solve problems involving systems modeled as a particle, system of particles or rigid body using the work-energy method and impulse-momentum method.

Course Objectives

• 1. Applying the concepts of kinetics and kinematics solve problems of engineering nature and show the understanding of the concepts by effectively communicating the solution in detail according to the standards of problem presentation for engineering problem solutions to be understood by engineers both in and out of the disciplines.
• 2. Draw Free Body Diagrams for systems modeled as particles or rigid bodies to apply the concepts of dynamics for analysis.
• 3. Describe possible types of motions for particles, and derive and apply the geometry of motion (displacement, velocity, and acceleration) for a particle using rectangular and polar and normal-tangential coordinate systems.
• 4. Describe possible types of motions for a rigid body and derive and apply the geometry of motion (displacement, velocity, acceleration) for a rigid body in translation, rotation about center of mass and in general motion in plane and in three dimensions.
• 5. Derive the equation for the system in plane motion relative to a rotating frame of reference and determine the Coriolis acceleration.
• 6. Calculate the work of a force using different coordinate systems and apply the method of work-energy and conservation of energy to systems modeled as particle, system of particles or rigid body in plane motion.
• 7. Apply the method of impulse-momentum and the conservation of momentum to systems modeled as particle, system of particles or rigid body in plane motion, also apply the concept of impulse and momentum to systems involved in direct, oblique and eccentric collision
• 8. Solve dynamics problems by selecting the best suited method or combination of methods and concepts for analysis.
• 9. Apply second law of motion to analyze systems with and without damping executing the vibration motion.
