I never got to thank you for your help, but those pictures really cleared up the difference between the two bearings. Thank you

I am having trouble finding the difference between and I beam Trolley with a roller bearing and a sleeve bearing? I know that the roller bearing has 4 wheels that sit on the bottom base of the I Beam and roll back and forth but I am not sure how a sleeve bearing is different from that? Thanks

I have remeasured everything and I believe my error was in the length to the bend. The value I was using was much to larege and by then adjusting that and making my dimensions more precise I got a much more accecptalbe answer

Yes I am using a micrometer and I remeasured everything like you suggested and found that some of my values were off as you thought they could be. The beam is 0.23 m long I merely forgot to change the number. I used the correct value in the calculations. I changed what values I was using...

The beam is 0.2 meters long and 0.0235m wide with a height of 0.0015m Stress = W/Z ( L – X) Z = I/y I = (B*D^3)/12 B = 0.0235 D = 0.0015 I = (.0235*.0015^3)/12 I = 6.609e-12 Z = I/y y = .5 (height) Z = 6.609e-12/.00075 Z = 8.81e-9 Stress = (49.05 N/3e-7) (.23 -.08) Stress =...

I guess then I am confused as to what number to use where. I looked back through all the links in post 2 and 4 and I thought B = length = 0.2 m D = height = 0.003 m y = half the height = 0.0015 m l = length = 0.2 m x = length to bend = 0.08 m This is what I thought the links that...

I use separation of variables with regards to the r component? x^2 + y^2 + z^2 and then use the schrondiger equation and solve it that way? by converting the x y and z component into sperhical coordinates?

Yes you are right i forgot to type that into the equation but in my calculation I did divide by the 12 so the results should be right and yes i am off by a factor of 10 which leads me to believe it is not in the equations but maybe the use of a wrong number

Yes I have. A long equation with partial derivatives

What is the normalized ground-state energy eigenfunction for the three-dimensional harmonic oscillator V(r) = 1/2 m* ω^2 * r^2 Use separation of varaibles strategy. Express the wave function in spherical coordinates. What is the orbital angualar momentum of the ground state? Explain? I...

Thank You for all your help. The links have been very helpful. This is all the work that I have done and I still seem to be getting the wrong answer The beam is .2 meters long and .025m wide with a height of .003m Stress = W/Z ( L – X) Z = I/y I = (B*D^3) B = .2 D = .003 I =...

What does the Z term in the equation represent? l = the length of the cantilever (m) x = the length to the bend (m) W = load (N)

Homework Statement I have a piece of metal with one end fastened to a table by a clamp and the other end off the table. I only know the length of the beam and the strain. I am trying to figure out the stress in order to figure out youngs module so the metal can be identified. How do I do...
