Spaghetti Bridge Challenge

I think that the most rewording part of this challenge was on competition day. this was the most rewording because it was when you get to see everything that you worked  for in action

Our bridge specific strengths were the two triangles that we had on either side of the  bridge.

If i were to make any changes now it would be that i would make it higher and more support beams.

some tips would be that don't do all of it the night before the day of the challenger

Reflections on mouse trap car project

In our mouse trap nothing really went wrong. There was when some dropped it on the floor and one of the CD smashed and we had to replace it. the things that went well  were that the first design worked well and we didn't have to change it . Our design was good because it went pretty far and it was pretty consistent as well. we also went to the finals in the drag race.

Tips
I would make so that there would be less resistance on the wheels. If i would do it again i would do much the same like giving wveryboady the same jobs.

Race Day

Our mouse trap car did okay I think. in the distance race our car average distance was 6.64m.our car was was pretty consistent.our farthest our car went was 7.19 i was happy with the distance it traveled.   In the drag race are car went all the way to the finales then lost.

the things that i would modify would be the axles. on the race they were a little bent and they would not roll in smoothly. and if there was some way to stop the resistance on the wheels i think that i would change the whole front wheels because they did not move smoothly and they would bend really easily.

if I were to redesign the whole car i would probably try to make it with only two wheels so there would be less resistance and the car and it would weigh less.i think that i would use a different string as well

FIRST POST

So this is my first blog ever!!  and i did it in physics class
