Trial #1 Peak Force: 69.7 N Impulse: 0.491 Ns Time: 0.016s Weight of egg: 60 grams On the first trial, our egg cracked upon impact. Once we let go of the device, it started to tilt on its side, which could have been due to factors such as air resistance or an unbalanced of weight on the device. Both factors caused our device to tilt. This caused the egg to fall on the side which was not reinforced as much as it needed to be. With the lack of straws on the side, where the impact occurred, the force was not as spread as we hoped, which meant that the egg experienced more force from the drop, which as a result cracked the egg. The lack of straws at the side also decreased the time for the egg to come to a rest, which meant we had a lower cushion than what we were expecting. In order to avoid these problems, we came up with a few ideas we wanted to implement in our next design. We want to create a parachute in order to keep the design up on its top and make sure it does not tilt on it side. We also want to have more straws on the bottom, since it will help us to have a higher impulse since it will allow more time for the egg to come to a rest and also to allow the straws to take most of the force of the drop rather than the egg. Our force is less than the initial egg dropping which means that there was greater time to stop the momentum of the object, which as result means that there was a greater impulse, which shows that the object was affected in stopping the egg hit the force plate with full force. Trial #2 Our device + egg: - Force: 62.1N Impulse: 0.4776N*s Time: 0.02secs Normal (Bare Egg): - Force: 71.8N Impulse = 0.461N*s Time: 0.014 In our second experiment, the impulse that our egg experienced is 0.4776N*s, and the force that the egg experiences is 62.1N. And the impulse that the bare egg experienced is 0.461N*s and a force of 71.8N. Based on the values that we have, the value of the impulse of our egg is more than the bare egg. And when comparing the force, our egg has less force compared to the bare egg. While comparing the force values between our egg and the bare egg, our egg had a protective layer around it to help absorb some of the force and reduce the acceleration experienced by the egg upon impact to the ground. However, the bare egg did not have a protective layer to actually reduce the acceleration as it was getting dropped. While comparing the impulses of the two we can see that the device helped create a greater impulse than just the normal egg, which means there was more time for the egg to come to a rest, since we can see that our force is a lot less compared to the Build & Test Reasoning: The Egg will be held by 4 straws vertically and 4 straws horizontally, forming a prism that will encapsulate the egg. There will be 2 rubber bands horizontally. The cage will form a triangular shape, which will be held together by tape. The straws that are purposed around the egg will have the duty to take off the brunt of the impact of the egg. Although the velocity is not reduced, the egg will have less force applied to it because the force is more spread out. The straws will be surrounding the egg, and then take the force from the impact and increase the time for the egg to come to rest. Padding from the straw is our main way of ensuring the egg will land safely.
