A little physics help?

[TheGr8Schlotzky]

I should be able to do this stuff, but I can't find my notes. I'll keep looking, but currently, i forgot the formulas for the pivot points and such. As you can see, i started the first one and wasn't sure what came next.. TIA

Sorry dude. If this was calculus, I could help you out I haven't polished my physics in a while though.

Re: A little physics help?

screw that! that's why i'm not going to be an engineer. i hate math.

Re: A little physics help?

I feel like the first one should be very easy, so let me go off the crappy (possibly inaccurate) notes in my head. It's basically just distance x force right? So it's just (92,000,000 x 1.32x10^25)/200 (assuming the guy weighs 200lbs).. so 1.22x10^33 miles......right?

OMG that is confusing./..lol im in geometry!:eek:

Re: A little physics help?

Now im a pretty tough kid. I go to the gym 5 days a week, take vitamins, protein, the works. Im one of the strongest in my weight training class, and Im a pretty good fighter as well.

this thead made me cry :slap:

Strength =/= toughness.

Re: A little physics help?

wtf does that mean? math hurts me lol. i aced algebra 1 XD.. but past that.. no good :(

Re: A little physics help?

Moments are easy. Just have one counter the other so there is no rotation.

1 A:
1.32x10^15lbs * 92,000,000meters = (his weight, don't see it given) * distance he must stand

1 B: 21Kg * 3.2m = T *0.6m

Just set the problems up, then use your algebra knowledge to solve for the unknown.

For problems two and four you're going to have to use Sin/Cos/Tan equations to find your distances.

I'm not going to do your work for you.

Re: A little physics help?

Almost forgot, pay attention to units and don't get meters mixed up with miles or anything like that.

For problem 3 just use the center of the beam for the center of mass.

What if Chuck Norris did it?????

He could do it with his pinky finger

Re: A little physics help?

The answers are ...... C ....... to all of them

That reminds me of that commercial where the guy had C for all his answers on that test

....what?



I figured out the first two by the time i read the rest of these responses, we'll see if i need help on the later ones.

It was an AT&T collect call commercial ............ like 1998? Dial right down the middle is what the guy said

Re: A little physics help?

Dude, this isn't physics.... this is dynamics. I love this stuff. Too bad you already have it all figured out though.
