What factors are considered when building a bridge and what's the physics behind them? Introduces the concepts of stress, strain, and Young's modulus to describe the structural properties of building materials. Examines the variety of bridge designs that these materials can be put to, how they work, and why. Also examines a bridge plan and uses concepts of torque and static forces to see if the bridge stands the test of its load. Sets forth a challenge for viewers to build and test their own bridges. Accessibility options on the DVD are: (1) audio description, (2) English subtitles in a black box.
