Some students benefit from having a physical, hand-held model which they can hold and experiment with. A group of faculty in biochemistry at NC State has been working on a Wordpress platform where lesson plans can be paired with 3D-printable designs for students to access. We propose to build a comparable site for Engineering Mechanics. Each lesson will include:
--written explanations of the topic
--a 3D CAD file using Fusion 360 where students can access the file, see how it's built, and edit it as needed
--a brief video from Fusion 360 where the part spins or deforms
--a 3D printer file so that faculty or students with access to a 3D printer can print their own demonstrations
--a lesson plan describing a simple experiment to demonstrate the topic being discussed
--reflection questions built around the material
The proof of concept is being explored using Area Moments of Inertia and Products of Inertia. This paper presents the initial feedback from students and instructor and plans for the future.
