The load cell was held relatively constant for 8 seconds and then released. We simulated one wave at 13 seconds. The load is in volts because that is the raw data acquired from the DAQ board. The conversion of volts to joules is in progress.
Circled is the time elapsed that is cause from the written acquisition program. Every 1500 samples (or every second) acquisition must pause in order to save the samples. We will continue to minimize this source of error.
You may see the actual excel file created by the program here.
