Mechanical Models that Move our Modern Machines
The Mechanical Library shows the mechanisms that make our world work.
This project is an open-source exhibit and curriculum for middle and high school students to introduce mechanical engineering. The “Wall of Mechanisms” motorized physical models each have a QR code linking to online information, videos, and 3D models that explain how they work and how they are used.
The Mechanical Library is inspired by the 1920's "Mechanical Wonderland" museum exhibit by W.M. Clark, which was inspired by the book "507 Mechanical Movements" by Henry T. Brown. More research and sources
We hope to support STEM education by sparking curiosity in how things work. Learn more about the Project
The exhibit is currently in early development, follow @mechanical.library and @SteveTurbek on Instagram

Mechanical Library Project Goals
The Mechanical Library is inspired by great science and engineering teachers worldwide.
- Inspire the 'engineering mindset' in middle to high school students, especially those not excited by math and engineering.
- Make something interesting for kids and parents to introduce Mechanical Engineering using practical demonstrations.
- Communicate the opportunities for a career in the well-paid physical technical fields.
- Support teachers who cover these subjects.
