1. ### Absorption Spectra

I agree, unfortunately I'm not comparing two spectra, but rather just answering for a variety of spectra is the solution optically dilute? Is it Optically thick? And not sure where the cut off is, can't find a value anywhere
2. ### Absorption Spectra

If you're reading a graph of absorption coefficient(cm^-1) versus wavelength(nm), how can you dtermine if the solution is optically dilute? What about optically thick? Thanks Ben
3. ### Impact strength

i've used plenty of google, the relative scale is not typically mentioned
4. ### Impact strength

I'm supposed to determine if a bunch of materials have a high or low impact strength. I did the hard part and determined that the impact strength for each material, but I don't know a relative scale. What is a high value on the izod impact scale test(it's measured in joules). Any idea?
5. ### Clustering Tendency

This is a general question, not specific to any one homework problem just a concept I must understand in order to figure out all of my homework. Does clustering tendency increase as atomic radii between substances A and B become more similar? Clustering tendency may not be particularly clear...

Hey guys, I worked through this problem and feel as though I made a mistake. I attached the figure, without it it makes no sense. Question: The suspended load weighs 600 lbs. Determine the reactions at A and B. Examining just the bottom bar, I summed the forces in the x and got Ax -...
7. ### Stress in a fiber

yeah I'm going with text is wrong, .125 is found by not dividing the radius by 2 and then dividing by a factor of 1000...haha only thing I could find out, but thank you!
8. ### Stress in a fiber

This doesn't seem particularly hard, thought it was simply an F/A situation but apparently not. A fiber with a diameter of 25 micro meters is subjected to elongation load of 25 g along the fiber axis. What is the stress on the fiber? Is the applied stress a shear or a tensiles stress. I said...
9. ### Convolution - prove commutative

anyone know how to prove that it is commutative... as if f *g = g*f
10. ### Solve for c/a ratio

thank you I was feeling like an idiot that I couldn't girue this out, I'm glad it doesn't appear to really be a trivial process. I appreciate the help, Ben
