Summary

Beam Deflection Lab

These 3D printed beams are used to teach students about the elastic curve equation, which engineers use to determine a beam's deflection when subjected to a load.

These beams are examples for instructors on how this lab can be performed. More information on this lab and other labs will be available soon in the form of a lab manual.
