The following materials are related to simple custom mechanical testing devices used to measure the mechanical properties of materials. The simple design of these devices helps students to understand the concepts associate with mechanical testing. These devices can also be used to develop activities for mechanics of materials and materials sciences related courses and for K12 outreach modules.
We welcome anyone curious about these topic to put together a testing device and try the activity at home or for instructors to use in the classroom, camps, clubs, etc. Feel free to email firstname.lastname@example.org with questions or to discuss.
This cheap and easy to assemble/use device can measure the breaking strength of fibers or yarns. An outreach activity linked to fishing line break strength is included below.

Fishing line strength testing
This device uses an air piston and bike pump to compress samples. We have used these in the classroom to measure the compressive modulus of porous polymer scaffolds.
