This morning was a continuation of of the work I was doing yesterday, finalizing the second design of the cantilever beam and 3D printing all of the designs. In the afternoon, the designs were able to be tested by putting them in a instron machine- a device that can apply extreamly high pressures, while being able to very accurately measure the force it was applying. After testing the breaking point of all four 3D prints, it was found that the second design to was significantly stronger, able to resist 160-180 pounds of force while the first design broke after only about 20 pounds of force.
