Yes okay I see that now, I re read that part of the chapter, I'll keep plugging away with the entropy section but I think I'm getting it now, thanks for the help! Its been much appreciated! have yourself a good weekend.

Oh okay I see that now, so yes if delta T went from Tinitial=10 to TFinal = 20, that is the same amount of heat transferred as Tinitial=50 to Tfinal=60. The amount they change by is the same. If you could answer one more question I would appreciate it. Its regarding expansion again, I can't wrap...

Yes sorry I was meaning to say I just wanted to focus on one part of the equation not to disregard work. I follow most of what youre saying its just the final statement I'm still struggling with. In my textbook I see for the sections on molar specific heat at constant volume as well as molar...

Thank you very much I read you post and was re reading the textbook, I worded my question way too simply and that caused my understanding to get muddled. So again please correct me where I go wrong but my textbook says in these exact words that the internal energy of an ideal gas is a function...

I'm having trouble wrapping my head around some thermodynamics and ideal gas law concepts. I don't have a specific textbook question but Just a concept I'm having trouble with. What I'm struggling with is understanding some of the relations between pressure, volume and temperature...

Interesting, okay so you are asking which point should I use as the pivot to eliminate tension? if that's the case then I would think using the climbers center of mass as that would be where tension would have a moment arm of zero. Thanks!

Thanks for the help, I think I need to stick with the problem a bit longer, the solution just seemed to use a lot of techniques that don't dawn on my immediately, so maybe sticking with it for a little longer will help me to see clearer a way to solve.

Thanks for some help! For the coefficient I'd need in this case the Normal force of her shoes on the wall to solve for Fs and I think tension in order to solve one of the equations that has one of the unknowns I need for the friction coefficient. I see the components I need, like Fs FN and...

Hello all, thanks for reading my post! I'm posting as I need help with my problem solving and thinking approach. For the most part I can figure out how to set up the problem and what I need to find, but my problem lies in textbook questions that rely more on seeing a more math based approach to...

Yes I see what youre saying, thanks for the help! I'll try and get a picture uploaded of my solutions tomorrow when I'm home to make sure were on the same page. Again thanks for the help, its much harder to figuer this out when its just all on your own :p

Oh sure thing, Ill be home tomorrow and will upload the solutions I have!

Oh actually I see now my mistake, since it is in equilibrium the hinge vertical force would be equal to the tension vertically and so that's how id end up with arcsin(mg/2T) NOT just arcsin(mg/T). Is what I'm thinking making any sense? Sorry I couldn't get a better diagram!

I also noticed that the equation used in the solution has θ=arcsin(mg/2T). Tension being multiplied by 2, which I can see from the algebra but the fact I get two different answers isn't making sense. I'm sure its not my calculator, since I end up with two different equation which doesn't make sense.

I thought since the hinge was chosen as the pivot point that the moment arm for it would be zero and then that would cancel it out? I'll upload a diagram from slader and have everything labeled

I've uploaded a linked image from google. Thanks for the help!
