ENG 220RC - Engineering Mechanics: Dynamics Recitation

1 Credits, 1 Contact Hours
1 lecture period 0 lab periods

Taken concurrently with ENG 220  in order to provide supplemental instruction. Facilitated discussions, discrete study groups, and collaborative problem solving provide more exposure to and more thorough discourse on engineering mechanics concepts and theory. Emphasizes applying mathematics, science, and engineering concepts to solve kinematic and kinetics problems; while providing opportunity to apply problem solving techniques and critical thinking. Study of the motion of bodies under the action of forces. Includes introduction to dynamics, kinematics of particles and rigid body, and kinetics of particles and rigid body.

Prerequisite(s): ENG 210  and MAT 241 .
Corequisite(s): ENG 220  
Information: Pass-Fail only. Students receiving a grade of C in ENG 210  or MAT 241  will be required to register for the ENG 220RC course concurrently; for students receiving a B grade or higher in ENG 210  and MAT 241 , the ENG 220RC course is optional, but highly recommended. Please be aware that if this course is not applicable toward your program of study, it is not eligible for the calculation of Federal Student Aid.
