Design Content Description

The design activities involve short problems that are given to the students in addition to the homework assignments. These problems address: (a) factor of safety and allowable stress, (b) selection of appropriate materials to meet certain criteria, (c) the role of mechanical properties such as ductility, compatibility, stiffness, and toughness, in designs.
