ATTN: Christophera re: Common Sense

GIGO

In college my calculator did not have a function to translate from rectangular to polar co-ordinates. however I could do it just as fast as those with newer calculators since it actually involved only about three extra key punches and I understood how to do it.

In tutorial we would be given questions to work out among ourselves. Everyone did their own calcvs then checked each others. many times I just glanced at someone else's answers and told them it was wrong and they would ask how I knew so quickly. It was because I could visulaize approx what the answer should be whereas they were just plugging in numbers and writing down what the calculator said. Often it was obvious that, for instance, they had punched in 2 instead of a 20. they simply did not understand what was being done.

One instructor deliberatly arranged questions so that one did not need a calculator and told us that we could do it faster without one.
For instance the question would have you dividing 4 X 105 by 2 X 103. While those who took the instructors words to heart simply wrote the answer 200 other guys would busily punch it into their calculators, often with hilarious results. One question ended up with the above 400000/2000 to get the final answer and the guy next to me wrote down 80 and I told him it was wrong. He asked how I knew and stated the obvious "that's what my calculator said". I pointed out that 4 divided by 2 is 2 not 8 and received a blank stare.

Now back to Christophera. He likely will not bother with your questions since they do not bear directly on his concrete core / C4 coated rebar postulations and thus he could not care less.
 
Where's my prize?

Unfortunately, I can't give you a cash prize. But in return for getting all the questions right, the last moment before you pass into the afterlife, you will receive total enlightenment.

So at least you've got that going for you.
 
Ouch, my head hurts! But I'll try a few :)
For each of these questions, provide your common sense, non-math based answer:
1) Structural Engineering

a) What loading per square length unit should be employed for office spaces in calculations for live load?
Live load includes office junk like desks, filing cabinets, etc..correct?
I'd say about 150 lbs/square foot(total guess)

b) Which will produce greater deflection on a cantilevered rectangular beam: A single point load at the end of the beam, or a distributed load equal to half of the point load over the entire beam?
Distributed load.
2) Physics

a) Which object has greater kenetic energy, a bowling ball weighing 5kg and travelling at 1/3rd the speed of light, or a freight train weighing 500,000Gg (giga grams) travelling at 50km/hr?
Bowling ball by a landslide.
b) Which is hotter: the surface of the sun, the core of the sun or the area immediately around the sun?
I read that the corona was millions of degrees, but I'll go with the center of the sun.

What kinda wacky gameshow is this? :confused:

So, is your common sense equal to, better than or worse than Christophera's?
 
This thread is not about common sense. And if Chris has any, he won't go near it. "Common sense" would tell him it is just a trap.

If he's got that kind of global common sense, shouldn't he also realize that 180+ pages of constant bickering about the same topic is going nowhere and quit?

Now there I did do the math. Even disregarding relativistic effects which would increase the mass the bowling ball wins.

I'd have guessed about 300 lbs/sq ft only because some offices had large safes.

Point load seemed too obvious so I'm going with distributed besides I don't remember my calculus enough to do the math.

Corona is hotter IIRC from a "Scientific American" article of this very subject last year. Its still a conundrum as to how it gets so hot but it seems to have to do with forces involved when magnetic fields collapse.

Wow.

Just wow.

Indeed, I stopped reading at the ANTAP mass insanity of 1876. Its not good to make light of people with major problems, so I wont - but I do think that Chris should probably be on heavy meds, and possibly a mental hospital...
 
a) Which object has greater kenetic energy, a bowling ball weighing 5kg and travelling at 1/3rd the speed of light, or a freight train weighing 500,000Gg (giga grams) travelling at 50km/hr

5Kg @ 100,000,000 m/s
5* (1 X108)2) = 5 X 1016 Kg-m2/s2______________________
500,000G grams =500 X 109 Kg
50Km/h=13.9 m/s

500 X 109 *(13.92)=6.9 x1012 Kg-m2/s2_________________________

The bowling ball has just under 10,000 times more kinetic energy than the train.

If the bowling ball was doing about 1/300 the speed of light they'd have close to equal kinetic energy.

If I were still in the work force, I'd go to the engineer down the hall, give her the questions, and politely ask "Can I have the answers by COB tomorrow?"
It almost always worked.
 
The answer to all the questions is 42. However, you asked for non-numeric answers, so I say the answer is "How many roads must a man walk down?"

This was the only obvious one for me.

the easiest way to solve that would be to use the E=1/2 mv^2. Since velocity is squared, and one third the speed of light is insanely fast, im sure that the velocity alone was enough to bring it past the train.
