Flamin' Heath Land Yacht

Aim
To build the fastest Wind racer out of the materials we were supplied.

Equipment 
Trolley (Cart chassis)
Cardboard
1 meter of paper roll
Scissors
2 meters of sellotape
Metal rod

Method 

1) Put the Metal rod into the trolley
2) Tape the strips of cardboard onto the base of the Metal rod so the base of the sail is formed.
3) Cut out a large triangle of paper and wrap it around the Metal Rod to form sails
4) Secure the sails onto the chassis with tape and tape any extra flappy bits down.
5) Make sure it is all secure and stable
6) Use the leaf blower to see how far it travels and the speed it travels.

Research

We took information from this website to figure out what shape our sails would be. We thought that the triangle shape would catch more wind and therefore go further than it would have compared to another shape. The triangle shape was quite a good choice and our design looked nice on that shape. We also want wheels on our chassis to be quite smooth but also have enough friction to stop it from completely falling over. We decided to put bits of cardboard near the base of the chassis just to ensure that it is still secure so it doesn't fall over and so the sails don't flap around.

Pictures 

Here we have some incredible photos of our land yacht. Molly painted Mr Heath on our land yacht.  Our yacht is called Flamin' Heath

Results 
The Velocity of our Land Yacht was 1.18MS-1
(at the time of updating my blog post, I forgot what the measurements were but I will update them when I find out)

To figure out what the Velocity of a moving object is, you need to divide the distance measured by the time measured.
Formula
V=⧍d/⧍t
The triangle means delta, delta means change. So the change of distance, divided by the change of time.

Discussion 
The initial launching of our land Yacht wasn't too bad and it did go 6.4M which was further than we thought it would be. I think if we used our cardboard more effectively by using more of it in more places nearer the base, we would have gone a bit further. I do think that for what we did, we got a good result. Molly and I worked well together and Molly did an excellent job with the designs of our sails. The science department seemed to appreciate the great feats of artistry. If we don't win most creative then I don't know what will.  I think that we did manage to make quite a nice land yacht. It didn't get very far but it went pretty far for what we had. During the race, if I had angeled the leafblower from a lower angle and happened to point it a bit higher up then it would have worked out a bit differently than it did today.


Conclusion 
In conclusion, the launching of our land yacht wasn't too bad and it went further than we expected. There are a few things that we would have changed such as the amount of cardboard and tape we used, but we are still very happy with the end result.

When measuring Velocity, be sure to use the correct formula.
