The data that came from our testing was raw accelerometer
data in the X, Y, and Z directions. The data was “raw” because it was unprocessed
values that came straight from the accelerometer. Over the 3 second period that
each test was being administered, the accelerometer took 300 readings in each
the X, Y, and Z directions. The next step is to process that data and further analyze
it to find the sweet spot of each bat.

Test Procedure and Results
Our test rig allowed a ball to be swung from a pendulum from
11 different heights which corresponded to hitting the bat in 11 different
spots. These spots were from 0-10 inches away from the bottom of the bat. For
each trial, a ball was released from 40 degrees to ensure that
the bat would be hit with a constant force. While the ball was released, the
accelerometer that was mounted to the handle of the bat was turned on,
recording 3 seconds worth of data.
