The nuts & bolts of building bridges. What factors to consider when you build a bridge and what's the Physics behind them? Introducing the concepts of Stress, Strain and Young's Modulus to describe the structural properties of building materials. This program examines the variety of bridge designs that these materials can be put to: how they work and why. It examines a bridge plan and uses concepts of Torque and Static forces to see if it stands the test of its load. Finally it challenges students to design and test their own bridges from simple materials.
