This video examines the use of welding rods in the construction of model bridges. Starting with an introduction to basic engineering principles, viewers learn about the loads and forces which affect all structures. Key concepts such as live and dead loads, structural failure, and thrust lines are explained in detail, along with an examination of the five forces of compression, tension, shear, torsion, and bending. These principles are then put to the test as students construct model bridges, using a limited amount of materials, which are stress tested in competition. It’s an exciting way to introduce the engineering principles of bridge building. One 15-minute video. A Shopware Production.
