# Dynamics

### 2nd Summer Session (June 28-August 7, 2017)

Course: CE 2080 Dynamics

Course Description:
Forces and force systems and their external effect on bodies, principally the condition of equilibrium. The techniques of vector mathematics are employed, and the rigor of physical analysis is emphasized.
2.000 Credit hours
2.000 Lecture hours

Prerequisite: ENGR 1090/ENGR 1410 (Clemson students only), Calculus III and CE 2010 (Statics)

This 5-week course involves the same rigor, content and workload of a 15-week Dynamics course. Since this course will move three times faster than usual, students should anticipate spending a minimum of 24 hours/week on this course. In order to be in the best possible position to succeed, it is not recommended that students do more than one of the following while being enrolled in this course: have a part-time job, enroll in more than three other academic credits during the same five week term, go on a family vacation, or commit to other activities with significant time demands.
