PHYS 215: Statics and Engineering Design

Catalog Description

Introduction to engineering design in the context of the basic mechanics of static structures and machines. Topics: multidimensional vector analysis of particles and rigid bodies in equilibrium, structural analysis of trusses and frames, friction, center of gravity, and moment of inertia. Introduction, by design project, to topics of technical drawing using CAD software, MATLAB and machine shop skills. Three lecture, three laboratory hours each week. Liberal Arts. This course has a fee. Prerequisite: PHYS 151.


There is probably no other science that is more important in engineering than mechanics, and no principle in mechanics is more important than equilibrium. Statics is the branch of engineering mechanics that focuses on equilibrium – the case where there is no acceleration and the total force and torque is zero. In this class you will become familiar with the application of equilibrium concepts to a wide variety of structures and machines. Moreover, in the laboratory you will learn how to apply the principles of engineering design, constrained by the laws of mechanics, to the design of a real structure – a balsa bridge.

Truss in space

A truss is a rigid structure that is made from members joined at their ends. Trusses can be very light, yet span large distances and support very heavy loads. This truss is being deployed from the space shuttle Atlantis as part of the Assembly Concept for Construction of Erectable Space Structures (ACCESS) device.


Landing Gear

The landing gear of an airplane is an example of a simple machine, which can be analyzed by using the principles of statics taught in this class.
