Contributes to the design experience and Engineering Topics courses of Civil Engineering and Environmental Engineering majors.

The design activity involves short design problems which are also incorporated into the homework assignments. These problems address: (a) factor of safety and allowable stresses, and (b) basic considerations for the design of prismatic beams and transmission shafts.
