Radius of Gyration

[Bray D]

low-five, nailed it.

Joe - it was a few semesters for me as well, I could SWEAR he gave us the "balancing a wheel" story in class. Anyways I busted out my statics book so here's a formal definition:

"The radius of gyration is simply the length that, when squared and multiplied by the area, gives the moment of inertia about the axis. Thus, for example, I=Ak^2" where 'I' is the moment of inertia and 'k' is the radius of gyration.
(King, Mcgill. Engineering Mechanics, Statics. 4th ed.)

Of course that definition is WRT area. The same equation still applies for mass. That definition sucks really, just describes the equation in words lol

I found a picture

Holy Cow! I figured this out just by that picture....the real answer is actually 3:05, but I'm not sure if that's AM or PM...

Guys, it's probably not helpful to do homework for someone else.

Even if he's stuck.

MAKG is right, good question, wrong forum. Maybe the ASAE

I am so not taking physics at NMC! blackbetty i feel for ya, I'll come over with some beer and we will work on something for the lift.

Wow, thankyou guys, I was just drawing a complete blank as to anything the teacher had said in class, or in his office, or at the bar (My teacher likes to drink and you get better grades in his class if you buy him a ). I remember him discussing the ring deal, but I was doodling suspensions or exo cages or something. I will pay attention when I re-take the class in the fall of 2010. Anyways, now I can finish yet another lab assignment. And all 18 of them will be complete.
