# STEMonstrations: Engineering Design - Trusses

The structure of the International Space Station relies heavily on a series of trusses engineered to withstand compression, tension, torsion and shear forces the station may encounter in low-Earth orbit. In this episode, Expedition 55/56 Flight Engineer Ricky Arnold explains the significance of these resilient structures and the forces they are up against in microgravity. Use the lesson plan that coincides with this video to emphasize the value of the engineering design process in your STEM classroom.
