Week 7 4/3/2018

Image
Today we started to construct the part of the Catapult that holds the arm in place. We might have to speed the building up because we are running out of time. We have two machines that we have to construct and update to make it work at the best of their ability. Our previous building on Thursday 3/22/18 went well and we managed to create the base of the Catapult. Hopefully building the main part of it will go the same way.

Week 6 3/22/2018

Today we created the base of the Catapult which went well. This consists of 5 25"  2 by 4's and 2 4' 2 by 4's. This was a simple part of the construction but will get more complicated as we progress. We hope to create the main part of the Catapult or build the base of the Trebuchet after we come back from spring break.

Today was the day we planned our layout of the wooden 2x4's for the base and other parts. Unfortunately we do not have enough wood to satisfy both the catapult and trebuchet. We are going to go back to Home Depot to purchase more wood. We also marked the wood with the dimensions we need to cut to accurately build the machines.

Week 5: 3/14/2018

Today we redesigned the Catapult to guarantee that it will work the way we want it to. Our design will include large rubber bands that will create power to launch the object. We will pull the arm back into a stable position and lock it in and release when we are ready to fire the catapult. The Trebuchet is almost the same but will be using weights instead of a rubber band.

On Thursday 3/8/2018 we went to home depot to purchase the wood and it went well. This was a lot of wood because we are building a Trebuchet and a Catapult. We hope to begin building next week if we get approved by Mr Martin. Our design for the Catapult was not up to par because our source of energy was not going to work. The Trebuchet design was good but we have to change the Catapult. Our design for the Catapult will be using Torsion. A rope will be wrapped around the arm of the catapult to create Torque and will be released.

This was another day of design and creation preparation that will help us for the following weeks to come. All of these days will get us one step closer to the building stage and will allow us to do it in the most efficient way possible. We are buying the materials for both the catapult and trebuchet today which is Thursday 3/8/2018. https://www.google.com/search?q=Catapult+wooden+base&source=lnms&tbm=isch&sa=X&ved=0ahUKEwje-eiRmt3ZAhUN11MKHcsjDx8Q_AUICygC&biw=1920&bih=949&surl=1&safe=active&ssui=on#imgrc=s65CZMNtQrdxEM: https://www.google.com/search?biw=1920&bih=900&tbm=isch&sa=1&ei=qmyhWpObO9H1zgKsjIq4CQ&q=Trebuchet+wooden+parts&oq=Trebuchet+wooden+parts&gs_l=psy-ab.3...55778.57241.0.57384.7.7.0.0.0.0.148.546.6j1.7.0....0...1c.1.64.psy-ab..0.3.194...0i8i30k1.0.Strbv_kaHBo&surl=1&safe=active&ssui=on#imgrc=O4N1EkdrwBrI4M: https://www.google.com/search?biw=1920&bih=900&tbm=isch...
