Hybrid User Quiz

Unread postAuthor: noname » Sat Sep 22, 2007 9:19 pm

I wrote up a quiz a little while ago, and if you are planning to make a hybrid, I'd highly advise you take it. All answers will be emailed to me, and you should put your SpudFiles username into the "enter your name" box.
The quiz covers basic principles of how a hybrid works, how to be safe with it, etc. If you don't score 100%, take the quiz again, at least 5 days later.
<a href="http://www.quizyourfriends.com/quizpage.php?quizname=070923114842-168418&">Take the NEW quiz</a>

I've edited the quiz. For all questions, choose the BEST answer, even if it isn't "perfect."

I really don't care, it's just that using your Spudfiles username would make it simpler. If I see a bunch of "Johns" and "Bob" and whatever (not pointing anyone out, just generic names) it would be quite confusing.

I'm not going to take the quiz now, but just let me tell you, having a quiz for competence with hybrids is a very good idea. The last thing we need is another idiot putting hydrogen in a coke bottle and having it blow up in his face. I admire your wisdom... :D

This quiz could use some improvements.

For question 1, options C and D are both correct.
For question 3, there is no correct answer in any of the options. The correct answer is 44.1psi.
For question 9, "Pressurize both the ignition chamber and the propane meter" applies only to some hybrids launchers.
For question 10, a 1/4" thick steel plate is NOT a good backstop (but neither are any of the other options), as many projectiles will ricochet off of it at high speed.

I would say that question 2 D is also true.
As long as you use small diameter pipe and use low mixes, it should work fine.

Some of your are giving the answers away, stop it. I'm a pneumatic man myself but i'm going to take it now anyway.

Edit: I scored a 70, not to bad.

You're too picky.
For question 9, I wrote that answer because the last 4 or 5 hybrids posted here have used that (your) design.
I wasn't thinking ricochets when I put down steel plate.

I'm making a new edited quiz now.
