Question

Comments/ critiques on my explanation and examples of lbl vs. lbf?

http://www.scribd.com/doc/85548870/Conversions-Involving-Lbl-Lbf-Lbm-and-Slugs

Are there any other good examples you can think of to give someone who is just learning the English system of force and mass?

Answer 1

Oops, typo on ex. 5. I'll fix that :-)

Answer 2

Don't worry I haven't get there yet =P

Answer 3

We need to comment a lot about the writting but the most important is to solve the problems. Sorry I'm a little to much slow =P.

Answer 4

That's okay!

I just had a lightbulb pop up in my head when I realized that I could explain this stuff better than how it was explained in the packet that my instructor gave me.

Answer 5

I'll return in a while, I haven't abandoned this thread.

Answer 6

ok

Answer 7

I have uploaded a revision of my document with more examples :-)

My goal was to beat the living hell out of this concept... a lot of the people in my class were just NOT understanding.

Answer 8

So is there anything wrong?

Answer 9

I don't know =(. Actually I did not know the unit called poundal.

Answer 10

:-)

Answer 11

The things your wrote are very logically indeed and it seems to me that is right.

Answer 12

But I'm not completly sure because I can not understand yet the conversion between slugs and lbm.

Answer 13

I thought that the lbm was a unit of mass. Now I'm very confused about it.

Answer 14

Slug to lbm is similar to saying kilogram to gram.

lbm is just a scaled-down version of slugs.

lbm and slugs are both mass.

Answer 15

lbl and lbf are units of force.

Answer 16

and what is the scale factor?

Answer 17

32.174?

Answer 18

1 slug = 32.174 lbm

Answer 19

and that is independent of the planet?

Answer 20

I meant... an object of a mass of 2 slugs on earth will be 2 slugs on Pluto... or wherever.

Answer 21

Ohh ok. I think I got it more clear.

Answer 22

Thank you brinethery!

Answer 23

Yay! I have educated an engineer in mechatronics!

Answer 24

hahaha I'm not an engineer yet =P

Answer 25

that's okay anyway :-)

Answer 26

I gave this document to my instructor and he really liked it.

Answer 27

But thank you so much. I need to think about these units systems a lot more. I always skip that part haha.

Answer 28

Yeah! is very good. Congratulations good job =).

Answer 29

you're educatin engineer all over the world.

Answer 30

that's awesome =P

Answer 31

I think once you really GET this basic stuff on lbm, slugs, whatever... then all the other stuff involving these units becomes really easy.

(But when I'm ruler of the universe, anyone who so as mentions gallons, slugs, lbm, etc. will be be-headed on the spot)

Answer 32

Thank you for all your support :-)

Answer 33

Haha I support you on that!

Answer 34

hahaha

Answer 35

Well have a good night brinethery. Now I can sleep in peace.

Answer 36

Lol... as long as you learn something you'll sleep well.

Answer 37

'night
