Aerodynamics
What is it?

• The science of how the air flows around the car.
• Down force - The more down force, the car has, the more grip it has and the quicker it can go around a corner, however it means that you have more drag and you go slower on the straights
• On Airplanes, the tips point downwards to create lift however on a car, the tips come up so that it stays on the ground. (creating downforce)

Recorder: Numbuh 1 and Number 2
Milestone: Prototype
Design amendments: We are using Popsicle sticks glued together for our base. and halved Popsicle sticks to hold the wheels together. Springs are loosely around the Popsicle sticks.

Scientific Reasoning: The springs allow for the base to stay on top and the wheels to still move. The Popsicle sticks are just used as a base to hold the wheels in place. The Popsicle sticks serve little to no aerodynamic purpose.
What will I work on next?: We will work on the rotation of the wheels for smoother movement. The base will also be changed for an aerodynamic purpose.
How will we do this?
we will glue the the wheel in place on the skewer and use the sprigs so the base can roll on top of the skewer.

Recorder: Number 2
Design amendments:
We are not using the Popsicle to make the body for our car but we started to us water bottle instead because it has car shape.

Scientific reasoning: we are using water bottle  because when we cut the bottle it has car shape. A car shape is more streamline, that is why we have decided to use it instead. We also have used Lego pieces with holes in them so the Popsicle sticks can roll freely with little friction.

What will  I work on next?:
We will work on making the design better. One wheel of this prototype is not touching the ground, but, it is an improvement from our last prototype. We also need straight wheel placement, our cars seem to always lean one way.

How will I do this?
We will  use a more appropriate base for our body, something with a better streamline for aerodynamics. Maybe use a lego for the base plate holding the wheels together. Lego is very square so we will get a straight wheel placement. We will also aim to get the same sized wheels.

We made a list of the problems of the first prototype and changed our design. Firstly, as the bottom of the chassey was made of paper, the wheels would keep on ripping off. Also the design of the car was not aerodynamic enough, it could have been improved as the wood created many bumps and areas that air could hit, it wasn't very smooth. On our second prototype, we didn't use paper, this made the whole product stronger, and we also used a water bottle for the outside body of the car so that it was more aerodynamic and smooth.]]> 2017-06-29 21:19:39 UTC https://padlet.com/161152/tw8elraqzagr/wish/177773160 https://padlet.com/161152/tw8elraqzagr/wish/177773542 - We need more stable wheels, as in prototype 2, the wheels were not strong enough, with the smaller wheels always falling off.
- Lights may be a nice addition to showcase our new knowledge and skills of electrical circuits.
- We could find a way to motorise our car.
- Have a better design beforehand.]]> 2017-06-29 21:25:28 UTC https://padlet.com/161152/tw8elraqzagr/wish/177773542 https://padlet.com/161152/tw8elraqzagr/wish/177773646 2017-06-29 21:28:03 UTC https://padlet.com/161152/tw8elraqzagr/wish/177773646 https://padlet.com/161152/tw8elraqzagr/wish/177773737 2017-06-29 21:29:47 UTC https://padlet.com/161152/tw8elraqzagr/wish/177773737 https://padlet.com/161152/tw8elraqzagr/wish/177773801 2017-06-29 21:31:16 UTC https://padlet.com/161152/tw8elraqzagr/wish/177773801 161152 https://padlet.com/161152/tw8elraqzagr/wish/178145286 2017-07-05 23:58:01 UTC https://padlet.com/161152/tw8elraqzagr/wish/178145286
