Our team constructed the first design using string, white wrapping paper, our package, a small cardboard box, scissors, and tape. Multiple drops took place and we noticed that the parachute is too small and isn’t working as planned. The force of the drops was still high and the speed is still way to fast for comfort.
In order to improve our design, we paid attention to area where it failed. The following “FAILS” happened during the drop:
The parachute did not bring down the force of the drop. The time it took the parachute to fall stayed the same as in Drop 0. The two data tables are shown below.
Drop 0 Data Table:
|Mass of Box (g)||Force||Accuracy||Velocity||Time (sec)|
|Drop 0 A||51.6||132.9||Barely on the force plate||12.6||0.3|
|Drop 0 B||51.6||126.4||Barely on the force plate||10.4||0.3|
|Drop 0 C||51.6||669.9||On the force plate||10.7||0.3|
Drop 1 Data Table:
|Mass of Box (g)||Force||Accuracy||Velocity (m/s)||Time (sec)|
|Drop 1 A||51.4||682.8||On Force Plate||10.6||0.3|
|Drop 1 B||51.4||724.9||On Fore Plate||10.4||0.3|
|Drop 1 C||51.4||302.8||Barely on Force Plate||10.5||0.3|
Some things also went well. Our successes include we have close to perfect accuracy and a reusable parachute that is hard to break.
For our next design, we will improve upon the first prototype by adding a larger parachute to our design to slow the fall even more.
