Just wondering, what have you heard about Columbia?

the beam does not have a mass...

I tried this problem again, and am still stuck. Please see the attachment for my work thus far. I know that I need to be able to pick an origin that will make the problem easier and cancel some stuff out, but I don't know what this is. any other help/ideas/hints? very much appreciated.

Please see the attached word document for the circuit and further explanation. any help would be appreciated.

oh, this is it Firestorm! can you help me out with some equations? I just need to be pointed in the right directions with some equations. any help you can provide would be great. thanks!

Thank you Steam King. This is the type of information I'm looking for. One hint I was given is to use a coordinate system that makes the problem easier to attack. I'm not sure what to do with that. Also, can you point me in the right direction with the basic statics equations?

Homework Statement A weight (mass given) is sitting on a beam that is supported by two columns. Given the location of the weight on the beam, calculate the force on each column. Homework Equations not sure The Attempt at a Solution not sure

sorry, you are right. Let me try again, can you help me convert energy (in Joules) to a mass (metric Tons) I can't figure out how to go about this.

Homework Statement The area of a copper plate is 0.1m^2. The coefficient of linear expansion (would be given in the problem). if the temperature increases from 22C to 100C, what is the new area of the copepr plate? Homework Equations L= LTá : but as alfa is linear Expansion coff...

any help would be appreciated. not sure where to start.
