Issues with calibrating the force pendulum
The software and force gauge did not take measurements well-- we are unsure of its accuracy. It seemed to max out well before its designated limit. We would raise the pendulum arm and release it to impact with the sensor. However, the force gauge would often move backwards from the force of the impact. We could not completely secure the force gauge and prevent it from moving. When recording the impacts, the graphs produced by the software showed strange data. Sometimes the peaks of force were in the negatives, and sometimes in the positive. There was no consistency, the data was unusable. Because of this, we decided to build our own force gauge to calibrate the pendulum.
