# Syllabus for GE 204se Statics for NCIAE

2018

## Course description

This course is offered in partnership with the North China Institute of Aerospace Engineering (NCIAE). Professor Xu Jingman (NCIAE) is the primary instructor and Dr. Rico Picone is visiting NCIAE for three weeks to instruct a portion of the course.

The following is the course description from the SMU catalog. Course represents the transition from theoretical studies of forces and equilibrium, as studied in physics, to applied science. The equilibrium of a particle when acted upon by a system of forces and the equilibrium of bodies in two and three dimensions are studied. Also covers equilibrium considerations for the design of trusses and machines, effects of friction on equilibrium and calculations of centroids and center of gravity.
