WTF

:ham: :bloated: :stuck_out_tongue:

Then it would not use a cross product, it would be T=dF

:word:

distance is a direction and value, hence a vector

This isn’t the NERD section.

BTW nice looking setup, I’m sure you’ll put it to use.

X…

I believe it would be foot lb., not lb. foot. This is what a 1000 lb ft Looks Like. lol

ha ha

Actually according to the [FONT=&quot]Commutative Property of multiplication it does not matter since you are multiplying the two factors therefore FtLb = LbFt[/FONT]

too bad that torque is a cross product, not multiplication.

fucking noob. lol.

46

lol, gotta love how Commutative Property of Multiplication was a copy/paste from Google in albaaboog’s post.

uhm read my post and learn the difference between scaler quantaties, vector quantaties, dot product, cross product, or take a basic dynamics course :bloated:

haha quoted before the edit

:word: That’s what I was thinking, that it wouldn’t be a cross product. But yeah, you’re right. Multiplying force x magnitude you’d just get a bigger linear force.

If we have a force F acting through a point P with position vector r with respect to O, then F and r lie in a plane through O. I have also redrawn the force vector F shifted so that its tail is at O.
The torque or moment of F about an axis through O perpendicular to this plane is given by

T = r x F = |r||f| sin t n

This is bugging me because it’s some basic physics that I just don’t remember. So is it just a convention that T = r x F and not F x r? To follow this convention the unit would be ft-lbs?

Don’t make me dig up my physics 1 book when I get home. :eyebrow:

yes it is ft-lbs, or (-1)lb-ft

51

the proper way is foot-pounds

52

I like the blue intake :gotme: lol.

53

So what we have learned is:

oh this is great. :lol:

I like ham.

What about how many watts would that be?

WRONG

POWER /= TORQUE.

come on dan, you’re an engineer.

do you mean joules???

watt ~ power = w/t = FD/t = mAD/t ~ kgm^2/s
ft-lb ~ torque = F X D = mAD ~ kgm^2/s^2
ft-lb ~ work =FD = mAD ~ kg*m^2/s^2 = joule

however, work is a dot product, torque is a cross product.

Soo… umm… So to me (1000Lb Ft TQ) seemed right, but now I have no idea what was right or even if there is a right or wrong wording of this.

the correct answer is ft-lbf, technically speaking as there is lbm and lbf
