Simple Machines Aren’t As Simple As They Seem.- Jessica Swofford

Hello and welcome back to the Jedi Design team’s blog, by Swofford! First I will update you all on what we have currently been working on, so you don’t think that I’m just randomly babbling about this.

Lately, my partners and I have been learning about Simple Machines. These machines include: a wedge, lever, inclined plane, wheel and axle, pulley, and a screw. The Simple Machines listed above were designed to make tasks easier for us to do. For example, a pulley makes it easier to lift a heavy object. There are MANY simple machines around. Much more than what we are learning about. My partners and I all didn’t know a hammer was considered a simple machine. We didn’t even think about a See-saw either! They are all around us,  and many are hard to notice or things that we wouldn’t expect. Part of the reason for us not knowing what is and what isn’t a simple machine is that there are even different classes that simple machines can go into. For example, a Lever has three different classes. The only difference between them is where the resistance(weight), the effort(your force that is added), and the Fulcrum(the pivoting point) are placed. A class one lever has the Fulcrum in the middle of the board( Or whatever object you choose to use) and the Resistance and Effort are placed on opposite ends. A class second lever has the Fulcrum at one end of the board, with the resistance in the middle and the Effort of the opposite side of the Resistance as the Fulcrum is. A third class lever is very similar to the second class lever. Instead of having the Resistance in the middle, the Effort is in the middle. So basically, all that is different is that the Resistance and the Effort are switched. Very similar, but they make a difference in the end. The magnitude of the forces, the placement and the distance away from the Fulcrum all contribute to the IMA(Ideal Mechanical Advantage) and the AMA(Actual Mechanical Advantage).

Not only have we been talking about different simple machines that could be used in our Airstream, we have also been talking about our teachers feedback and what we should ABSOLUTLY have in the trailer. The majority of the teachers that the Jedi Design Team interviewed wanted the colors of the trailer to be calming, relaxing and maybe a bit pastel. One idea that we have and are debating is to have the colors a light blue and brown, or fall colors like the leaves. Auburn and a good shade of brown. Another feature that the teachers definitely wanted in the Airstream is couches. We have been trying to incorporate these into the floor plan and a high possibility that we are considering is to have the couches at the far end of the trailer, away from the door, and have them go with the curve of the Airstream.  I have been researching Airstream remodels and how other people have used the space given and my team and I believe that having the couches in one end and not in the middle or the side uses the Airstream’s space a lot more efficiently.
