Bumping this because I found some new info! Apparently (digging through other forums, and looking at old textbooks from archive.org) -- there actually used to be TWO systems of English units taught in the United States, and Great Britian. One system used pound as a the force unit...

Oh okay! This makes a lot more sense thank you!

But y'know since i'm student i don't really know. I've only just come to ask people who know more than me. I could ask my tutor but it's Saturday.

Lol what type of question is this? If you're for real -- I was browsing the internet for hw solutions. Came across this problem. The question asks to find the modulus of toughness and resilience. I'm figuring since the above one has actually shows the curve that i'm used to (yield point...

Well... it doesn't

I don't know if i'm exactly right. But I started with x(time) = V cos θ t which = (6810 m/s) cos (69.1°) (11.4 * 10^-3 s) is ... 27.69 m & since Electric field due to uniformly charge surface is represented by... E = (q * σ)/(2 * ε_0 * m), and since acceleration (a) can be expressed as F/m...

Can't say I use much SI besides in my Physics I & II In most of the classes related to engineering & design. It's almost exclusively in British Units. kip, psi, psf, lbf*in, mile, yard, etc.

I'll see pound-mass (lb-m) & slug. I'm an undergrad student and always confuse between the two at times. It seems to me slug is a lot easier to use at times (given its easy conversion into force for most problems) (i.e 1 slug * 1 ft/s^2 = 1 lbf) What's even the point of putting lb-m in most...
