Air Trajectory B/C

Okay. Thanks!

Be sure to note that 3.h. prohibits electrical components as part of the device or triggering device. It was mentioned in last year's thread that lasers could probably be used only if they were removed from the device prior to each launch. There was an FAQ last year about it (http://www.scioly.org/phpBB3/viewtopic. ... 97#p275297) but keep in mind that last year's FAQs do not necessarily apply to this year's rules.

I wasn't wanting it attached, I was wanting to hold it. Would that be allowed?

Seems like it'd be allowed, as long as what you do follows the event rules and laser policy on the national website. How do you plan on using a laser? If to help with positioning/angling of your device, it may be better to allow the laser to be temporarily fixed to the device, since for far distances, a slight difference in how a laser is positioned can result in a point tens of centimeters off.

Good point. I will probably do that then

In 3d., it states that the mechanism must stay withing an 80 cm cube while in a launching position. Does that rule apply for when the mechanism launches, i.e. the arm goes over 80 cm high and then returns to the cube while launching?

By "ready-to-launch configuration," the device seems to only need to fit within an 80 cm cube at the start of launch, not after.

Ok. Thanks! Is there a weight limit for the launching mechanism? I'm not talking about the weight, but the actual launching mechanism

For the entire device, there is no minimum or maximum weight. You'd probably want to make it easy for transport through. To avoid the device moving as the weight falls, I've seen teams add dumbbells or other weights to their device to hold it in place, but the weights are transported separately. Cork or rubber feet are also good to prevent your device from shifting. You probably wouldn't want a device so heavy that you might drop it while transporting.

Just wondering what would be a good container/ weight for Air Trajectory

I have seen many teams using dumbbell weights

We melted lead into a soda can. Works nicely, but was relatively difficult. I believe our AP Chem teacher supervised the whole thing which took place in a fume hood (lead is poisonous). An easier solution is using dumbbell weights.

We're just dropping a standard 500g circular weight. Like the ones you would use in a physics class

And you are able to reach the full 8 meters?
