Students experiment with the five fundamental load types that can act on structures. They use foam insulation blocks to which they apply the forces and draw the fracture patterns. They determine the telltale marks of failure that is caused by each load type. They determine how engineers have to plan for these forces when designing buildings. Full Review »
