Quick question - centre of gravity/mass
Hi there,
How do I calculate the centre of gravity/mass of a 2m long bar that varies from 10kg/m at the left hand end to 5kg/m at the right hand end? Thanks |
Homework time again? Looks like the school year has started.

Edit: Okay - as per <b>Halx</b>, "The Tilted Knowledge forum is basically a place for you to ask for secular knowledge such as mathematics and grammar." Therefore, I will withdraw my comment, and change it to: "Read the damn textbook." :D |

OK, I'll be polite as well then. If you have lost your textbook, you can do it through geometry, changing "mass" to "area". Basically, you end up with a triangle; figure out where the line is that gives you equal area on each side. |
Does it change uniformly along its length?

Thanks for the tips guys, problem is, this is a set of questions I have been given to prepare me for my University course, and I'm not at University yet so I don't have any of the textbooks. |
Well, if you Google using "center" instead of "centre", this NASA page is pretty cool. Again, convert "mass" to "area".
|
OK thats great, I managed to do it using the area idea. Thanks again.
