Author | Topic: Using your common sense to solve a physics problem. | |||||||||||||||||||||||

Again, we didn't discuss nut or rod sizes, and I didn't engineer the whole thing from the start. Its called a trick question, and it didn't even give enough information to figure out the correct answer, like rod sizes, and wieght of the catwalk.
Its just hogwash.

The NEWS REPORTERS are telling you, usually really poorly, the results of some study. If you decide to change your behavior based upon hearing a soundbite you heard on the evening news, that's your problem.
Oh how I hate the news. Its all BS.

That last point is counterintuitive, isn't it? That's why this problem is such a wonderful example of the insufficiency of common sense for much of problem solving. You've discovered that your common sense has failed you, and that your lack of knowledge has become a significant obstacle. You've been reduced to slogging your way through what is actually an extremely simple problem in mechanics. And you can't even cite your lack of college training on this one, because this is basic high school physics.
I dropped out of 10th grade, never even made it through 10th. I was too rapped up in hanging out, and smoking pot, because my parents were to busy arguing with each other. Then I started working and never went back to school. It sucks because I could have been good in college. So I never even took physics in HS. I could however figure this whole thing out on my own, without any formulas, and just using whats at the scene of the accident. My common sense would lead me through. This would be a great undertaking, I know, and I will never get to prove it. But I enjoyed this problem so far. I fully understand all the forces on the car and what happened. I just don't know how to express it verbally, or mathematically using the formulas given. This still doesn't stop me from knowing what happened.I want everyone to just stop thinking that I hate engineers, and scientists, and whatever. Thats not the case, and I have great respect for the good ones out there, as well as all the knowledge gained over the years from all the work done by the great ones. Thats all I can tell you from and its coming from a jerk Christian

I could have been good in college. You know, there are hints that this is correct. You have a long way to go to be able to apply the talent you may have but it might be there. You're going to have to listen to some input a lot better than you have though. You'll have to stop assuming that you know a lot more than you actually do. You'll have to be able to handle some deeply disturbing, to you, ideas and understand the logic behind them. It's a lot. Good luck.

I asked you for the rammificatoins of the change. You said that the rammifications were that it had to support a few more inches of rod and an extra nut. You never even mentioned the increased tensile load on the first nut. Are you going to try and claim that you thought of it, but didn't think it was important enough to mention it? Because it most definitely was a serious ramification.

I can agree on all that, thanks for the input.
I do respect your opinion.

revelation, schraff is the talkorigins poster girl
Thanks schraff, I really wish I had the time to go to college. If I did it would be more aimed at my current profession.

I'm saying gravity is straight down. They use the perpendicular pull on gravity relative the surface of the earth to figure the force on the car. If gravity is not exactly perpendicular, its affect is different. Ok, now I see that you're on the right track you're just wording it in a confusing manner. I'll put up my step-by-step solution in about 3 hours unless theres any objections?

crashfrog responds to me:
quote: Clever, but not quite what I had in mind. That is, your words do contain the word "eight," but I said "eight words," and "eight" is singular in that it is only one word. When I said "eight words," I mean if you take the letters of the word, read them left to right, without re-ordering, you'd find eight words: He, height, eight, eights...that's only four. Rrhain WWJD?

Clever, but not quite what I had in mind. Worth a shot. Now that I understand your problem, it's too hard for me.

crashfrog responds to me:
quote: No, it isn't. Like the original physics question, you have all the information you need to solve the puzzle. And no, I don't mean doing something like looking up words in a dictionary. Look at the puzzle again: Two common, seven-letter words, each of which has eight words within. One is different from another and therein lies the answer. Rrhain WWJD? JWRTFM!

Check your spelling, jar. "Ether" does not appear in "another."
