I did use J/gC for specific heat. The operation you are proposing cancels all units and leaves you with a dimensionless number if i am looking at it correctly. Thank you for trying to help, I think we might be on different pages. I found something more geared towards what I'm looking for here...

4.21/334 is not 79 you are correct, it is .0125. The problem is that I still have the C unit left in the denominator when everything else cancels. I would think that you would have to take the inverse of .0125 (79) to get the temperature unit into the numerator and get my answer. My notation on...

I guess I don't see what I did wrong. Would you elaborate?

Hello, I am doing some research involving supercooled water flash freezing into ice. I am doing some calculations and I think that I must be wrong judging by my result. Using the latent heat of fusion of water, and the specific heat of water, I can calculate a temperature value which should...

Homework Statement What is the maximum flow rate that can be seen in a water pipe where city water is supplied to a building. The pressure behind the water is 50psi, and the inner diameter of the pipe is 2". Homework Equations bernoulli's principle The Attempt at a Solution I...

You the man SteamKing. So it is definitely treated differently for structures than it is for solid parts like I usually deal with as a mechanical engineer. When they determine that the live load rating is 100 PSF what assumptions are made? For example is that the 3000 pounds of force can be...

So I'm looking at some technical drawings here (mechanical engineering co-op) and the live load rating is 100 pounds per square foot (PSF) for this particular drawing. My question is this: why is it so low? Just me standing with my feet together exerts roughly 230 pounds per square foot (i'm...

When combining the fixed end reactions using superposition, are you just adding them? For example the moment at A would be the sum of the moments at A for each of the three loads? If so I think I have finished. Here is a link to a google doc containing the shear and bending moment diagram I came...

For my case, (http://imgur.com/XmgNq11) how do I find the equivalent force (P)? I was thinking sum the moments about one of the supports to find a force and distance that gives an equal moment but I would have to use the reaction moment/force at the other end, which I don't know. Is there a...

The problem I'm running into is that I cannot construct the shear and moment diagram with the information given after they sum the forces and the moments, it is statically indeterminate. I can get equations for the reactions but I have too many unknowns. Are you saying to just construct the...

Sweet! I knew it had to be something simple like that. If you have enough patience for another question, where are the 'force-displacement relations' coming from? I have tried google searching but wasn't having much luck on that specific subject as it relates to the form these equations are in...

Thanks for the reply, I was looking at the pdf you linked for a while before I posted here and was having trouble following along as they seem to skip steps. In particular, in example 10-4 (which if I can work through is very similar to part of my problem) they go straight to an equation R_a=...

Homework Statement Find the shear and bending moment diagram for a fully restrained beam with a length of 5m, a uniform distributed load of 1kN/m from x=0 to 2m, a point load of 1kN at 2m, and another uniform distributed load of .9kN/m from x=2, to x=5. Homework Equations The...
