Okay, so member force = axial force, right?
Sorry for the really stupid questions! I am taking a continuation of a course from last year and the teacher uses different terminology, so I don't want to lose any points because of terminology.
And thank you, again!
Homework Statement
Determine all the member forces in the truss shown below, and identify tension/compression for each member.
I know there was more to what I was supposed to put here, but I really only have a terminology question. I know that I have to determine all of the reactions...
Okay, so what I did now was set 95 = 1240 / [(-13.6/n^2)-(-13.6/25)] and solved for n, but I am getting something between 1 and 2, and not really very definitively either one. You can't be between energy states, so I know I must still be doing something wrong.
Thank you for all your help so far!
Does that change my equation for finding the initial state, or just for the final state? And for the final state, I tried to find E with E=hc/lambda, and then plug that in as the final energy, but that didn't work. I got something less then one.
Homework Statement
A hydrogen atom in an excited state emits a photon of wavelength 95nm. What are the initial and final states of the hydrogen atom? [Hint: you will need to make a reasonable guess of what is the final state. look at the energy of the photon and compare this energy with all...
