Explore how the molecular structure of metal affects its mechanical properties. This model shows a metal lattice, such as aluminum or iron. In this model you can use a downward force to bend a small metal beam. Use different amounts of force to bend the beam. What happens to the beam when you use a small force or a large force? What happens when you release the force? Compare the structure and behavior of this beam to the ceramic beam. How do their behaviors differ and why?
