Top Loading Test
Summary of Test
The top loading test for the project was to test the requirement for the standard weight limit of 2.5 lbs. for the project. This top loading test would ensure that the support arm would not break under the weight of the mirror holder. The mirror holder itself is only around half a pound. The support arm was not tested to failure. It was tested to 3 lbs. and the deflection was measure as well as if the support arm survived the loading.
Reflection Distance Test
Summary of Test
The reflection distance test was designed and created to test the reflection distance of the mirrors. The minimum requirement was 200 feet. This test was done outside to test it in the natural elements like it would be if it was attached the electric vehicle. A diagram of the test is located below.
Mirror Rotation
Summary of Test
This test was used to measure the angle of rotation of the mirrored surface. The requirement of the test was the mirror needed to rotate 15 degrees in either direction. This test was done inside and with good lighting so that an accurate degree of rotation could be found. This test was simple. It only need the a pencil, a piece of paper with degree lines made and the mirrors themselves.
Weight Test
Summary of Test
This wasn't necessarily a test but it was done to ensure the mirrors were under the one pound requirement/ The only thing done for this test was to weight the mirrors on a scale.
Mirror Surface Area
Summary of Test
According the Electrathon Handbook/Rulebook, the surface area of the mirror(s) have to be at leas 8 inches squared. This wasn't a test either, it was design factor that was done as the project was being designed. So as along as the mirrors printed out to the correct size, the surface area requirement would be met.
Side loading/Drag Coefficient
Summary of Test
These two tests were not done because there were limitations and accessibility to material that were an issue. The Side loading for the project had to be 200 lbs and without the proper equipment the test could not take place. The drag coefficient required a .4 ratio, but without access to the wind tunnel the test could not take place. To get a full scope of the design adequacies, these two test should be done.
Testing Issues
Top loading
All the tests presented all had issues because things had to be improvised. However, one issue was the top loading test was supposed to use instrom testing machine, but due to Covid-19, the test had to use alternative methods to test it. Instead of using a machine, basic weights were used and a ruler was used to get the deflection. This allowed for the test to get done and for results to be recorded.
