Re: Gravity Vehicle C

So yes, if you look at the Vehicle as a closed system, at the end of the run, kinetic energy has to be 0. If you haven't stored any of that kinetic energy in something (like elastic or gravitational potential), then it all must have been dissipated as heat by your brakes. Actually, magnets might (e...

Re: Gravity Vehicle C

This brings up an interesting point of discussion: would it be possible to move the center of mass during the run of your vehicle? In the ready to run position, Id estimate wanting about 90% of the mass in the rear, but after the vehicle has descended down the ramp, it is more advantageous to have ...

Re: Gravity Vehicle C

I don't know if this is appropriate to put here but I wanted to get other's opinions on this: Why would they make the distance so long? 12 meters?!?! This may be unique to my situation but the way our team does building events is the kids do it 99% at home. Most building and testing time is done on...

Re: Circuit Lab B/C

I have a few questions regarding the Circuit Lab test for C division. What types of capacitors will we need to know about? Is it just parallel plate capacitors or also cylindrical, spherical, etc.? What do we need to know regarding AC Circuits? Will we be asked to do calculations on AC Circuits reg...

Re: Gravity Vehicle C

What's the legality on this, given the phrase in 3.g. "All parts of the Vehicle must move as a whole"? That's a curious phrase - "move as a whole" isn't very well defined. The next clause talks about no anchors or tethers, so I'd interpret that to mean "everything has to stay with the car" but I wo...

Re: Gravity Vehicle C

Do you think there is any best size for the car to be? Old pictures seem to indicate a wide variety of dimensions. Some covered the whole ramp and others were probably not even 25 cm long. I believe any size vehicle has the ability to work out well, but personally I think bigger cars are the way to...

Re: Gravity Vehicle C

I understand, thanks for the clarifications. I planned on launching the vehicle from the top of the ramp but adjusting the mass concentration on the vehicle to regulate how high the center of mass is. My current ramp design features barriers on either side of the ramp that extend 1.5 cm above the s...

Re: Gravity Vehicle C

Given that the time is now taken by two photogates (one at the .5 meter mark and one at the 8.5 meter mark), teams can now adapt their vehicles to brake over a distance of half a meter because the shortest distance it will have to stop at is 9 meters. This 0.5 meter buffer distance would allow for ...

Re: Boomilever B/C

Uhhh unless I completely read that wrong the boom must be OUTSIDE the 8cm lines, not inside. So they would have to be wider, not skinnier.
This is correct
