Re: Trajectory B/C

The competition was held at my college where there are plenty of rooms with a high ceiling. In fact, Mousetrap Vehicle and Mission Possible were held in a room with a ~25 foot ceiling, and Trajectory was held in a hallway with a ~12 foot ceiling. Makes no sense to me - let's have the events that st...

Re: New York 2009

Hey, congratulations to everyone that was there. I was there too, but I didn't recognize anyone as I'm not to familiar with the many of you here. Unfortunately my team didn't receive any medals, our best was 8th in Egg-O-Naut. But I'm glad I did somewhat well in Trajectory and Physics Lab, however i...

Re: Trajectory B/C

they never put it in a cube they measure it with a yard stick
Actually that's not true. At our regionals the event coordinator has built a transparent cube out of some wood and plastic. It ended up being quite annoying fitting everyone's devices in there but that is what they used for the event.

Re: It's about time

Yes but with a longer pendulum I thought the period would be too long. Therefore can you get an accurate measure of time to be close to the .1 sec requirement? How would you read the final place of the pendulum and correspond it to the time if it's not at the end of its swing?

Re: Trajectory B&C

I'm pretty sure it was 8 meters, but I may be wrong. If it wasn't that then it was probably 6 meters. I'll ask a friend tomorrow.

Re: It's about time

Well I've been reading this discussion - and it seems a lot of you are using pendulums. Are you just using a simple pendulum with no escapement then? Like you just count the number of swings yourself?

Re: It's about time

I've just been placed on this event for the state competition. I was thinking of possibly making an escapement pendulum to track the time. I just wanted to ask anyone here that has also made an escapement clock to ask what they used for the actual escapement gear? Because I know we aren't allowed to...

Re: Trajectory B&C

I can remember at my regionals the targets were at 4 meters and 8 meters with the 4 meter target elevated 130cm.

Re: New York 2009

Oh, then maybe that's the reason why. I found out that Springville was being included as a bonus team, so I just assumed that was because they were only two points behind us. You're probably right that the reason they are going is because Will N. has gone three years in a row.
