Future recomendations, trebuchet

Things that went well for our group and trebuchet was that everything worked as it was suppose top and Murfey's law didn't effect us. Future recommendations I have for other teams is to make sure your sling is perfect. the sling is one of the most important pieces of the system and if it is not good your trebuchet will shoot up and backwards.

The accuracy part of the contest was where we did best. We landed two shots both .24 meters away from the targets center. I f there was an opportunity I wouldn't change much, the trebuchet did a good job and only could have made the release a little sooner. If we could rebuild the trebuchet I would only want to change the pouch and make a safer/better working trigger system.

The picture is of the marker we used to show how far away our ball landed.

Post 4 Trebuchet

Our trebuchet's performance in distance was great. We achieved an average distance or 51.06 meters. We could have had a better sling release and trigger system. We planned to remove a great deal of the weight for the accuracy portion so that it wouldn't go as far.  

Post 3 trebuchet challenge

The theoretical range of our trebuchet was 1442.30 meters. the actual average distance the ball traveled was 51.06 meters. The reasons our trebuchet didn't go the theoretical range was due to air resistance, gravity, also the wind pushing the ball to the side, and our performance factors were not dial in perfectly. the photo is a picture of our trebuchet ready to fire.

Our cardboard trebuchet work very well, it took some time to get it going but then we found the right weight amount. The environmental factors that effected our trebuchets work was gravity and air resistance. the performance factors are the factors of our sling such as the length and the amount of weight we put in the basket; plus the angle of release being one of the more important ones. The picture I was to put on didn't work.

Egg drop, Post two!

Our container was 12 cm/12 cm/ 22cm. it weighed 75.59 grams and fell 5 meters in .99 seconds. The eggs condition was perfect earning us a total 264.9 egg points.the most effective part of our design was the sponges they are light and soft absorbing all the force without adding weight to the container. the least effective part was the weight of the container, if it was lighter we would have gained more points. To make it able to carry two eggs the design of the container would be changed; the two eggs would be half in one sponge (whether the top or bottom, one in each) and the other half of each would be in the middle sponge.

Egg drop, Post one!

Test day for our container was a success. We each created our own container and they each worked the same, we went with my design because of the weight difference and mine was lighter. First we tested each container at the highest point of the stairs each keeping the eggs in one piece, so we tried a little more force by kicking it at a wall before it fell and it also survived. The only changes we made to the container was added lighter string. (Video by Melissa)
