Thankyou enigma

How do i use html? just past the code or do i need to be in a different mode? http://img.villagephotos.com/p/2004-10/844417/Image2.jpg lol we'll see Fixed your link, SheCanBuild -enigma

Please explain how I calc the hydrostatic force and it's location on the plate. Above the drawing is says: A 10m equlateral plate under water Assume 60 degrees F I clicked on 'Manage Attatchments' to upload the drawing. Give me a minute to do it another way if it won't show up...

Here's the question exactly how it reads in the handout: 'What is the difference in weight of 50 gal of water at 39F and at 77F?'

Aww man now I'm confused. Yeah that's what our debate was all about. They said what equals mass? and considering that made me wonder. But proof? Sure I can do the math and get the difference, but am I going to be right? Can I proove it to myself with the results? Thanks again, Ronelle

Well he only 'mentioned' the fact that mass never changes (just the volume) He told us that about 45 minutes before he assigned the questions and left. (we have lab time he uses to make us work on concepts) I think it was a suttle hint knowing what he was going to assign. Anyway we all...

Or would you just say the weight stays the same? Knowing what little we have learned, do you think that's the answer? btw thanks ; )

Well what's that? Sorry I'm only a second yr student, and have had just basic physics. This is for engineering (hydraulics) I'm sure we'll get to that, but havn't yet. is e=energy? LOL and is c celcius? NO laughing please lol

Hi ya'll, We debated in class...Dr Mir had clearly stated during his lecture that the mass, of water won't change even if the temp does. He said "yes the volume will expand and contract, with temp change, but the MASS won't" Anyway he assigned this question: 'What is the difference in weight...
