Rubber Band Racers |

---|---|---|---|---|
|
||||
1/. The first RBR Research Project, is to look at Speed of the Fastest Moving Machines. |
||||
|
||||
The second Research Project is bases on actual RBR's. This is another slideshow project, |
||||
|
||||
1/. List all it's components, also showing quantities. |
||||
2/. List it's speed attributes. |
||||
3/. Explain why it is the best RBR, which is why you chose it. |
||||
We are working on a prototype design which you will be able to create a design on the body of the rbr and then assemble your own rbr. |
||||
|
||||
|
||||
Finally the Design Project |
||||
|
||||
|
||||
|
||||
The Construction: |
||||
1/. Sandpaper the edges and wheel rims. |
||||
2/. The sides and ends are to be glued together using PVA glue. |
||||
3/. The two doweling axles go into the holes. |
||||
4/. The gaffer tape is to be cut into widths of 10mm. Two pieces of gaffa tape are used as the outer hub on each wheel. |
||||
5/. Once built, test the racer on the floor and on the supplied racetrack. |
||||
6/. Make any modifications necessary. |
||||
7/. Have someone with a stop watch test the speed of your racer - how many seconds from the start to the finish. Record the timing and compare with others, to find the first and fastest rbr, the second and the third. |
||||
8/. Record the best speeds of your racer. |
||||
9/. Race your rbr with some other racers, note times for each on an excel spreadsheet file. |
||||
10/. Work out the placings and add this information to the spreadsheet. |
