Hello good evening, I have doubts about indicating the harmonics or bands in this spectrum that is from a reduction box, to try to identify if there is an imbalance or misalignment or other problem. Can anyone help? Thank you.
Rb1957 is right, don't waste any more time, as such a complex and difficult-to-understand analysis, will not be necessary for this work wich is a simple school projet, but it was already possible anyway for learning how structures work and other solutions such as the Moment Area method and the...
BA do you agree with this ? In the horizontal defletion SD=SC=155P*200^2/2E1 why is E1 It shouldn't be E2?
In the vertical defletion the term PL^3/3E1=5*310^3/(3*130.4e6) could you explain?
Rb1957 it is a simple 3D part on solidworks.
Thanks
I understand butt the linear straing gauge is on the x axis position. So responds to bending moment butt analiticaly is zero.
Mfx=265*P
Analiticaly Sigma x= (Mfx*y)/I=(265*P*y)/I)=0
The Experimental value that obtained for 5 [N] of -0.229 MPa and deformation of -3.330 us shows that is reading...
BA I was checking your calculations, however I still have some doubts about how you arrived at some equations. Can you check if the sketch I made corresponds to the displacements and slopes?
Why thetaC is the sum of thetaB and the change of slope between BC? Shouldn't be only the change of...
BAretired could you explain how do get 232.5 value on tetaC.
You can make a sketch of what each calculation refers to as I did in the diagram. It's hard for me to understand.
I experimentally obtained from the dial indicator a displacement for a load of 5 N of 1.491 mm and for 7 N of 1.931 mm...
BAretired its aluminium alloy 6063-T6 E=69GPa
For tube AB and CD: (Do=15,6 Di=12 mm)
i'm calculating I=pi*(15.6^4-12^4)/64=1889,26 mm^4
So EI=69e9 (Pa)* 1889,26e-12 (m^4)=130.36 N.m^2
For tube BC:
I=(20x10^3-17x7^3)/12=1180,75 mm^4 (the tube its 20x10x1,5 mm)
So...
OK. rb1957 I had calculated again. i'm not considering the displacement due to shear, do you think it is significant?
Should i use Deltax=(Tau * L)/ (G *A) ?
On the AB tube:
I was using x (0 to 310 mm) on first post. But i think its (0 to 150 mm ) on AB tube. it is right?
Now for a P=5 N i...
Hello again.
I am calculating the displacement using the Castiglian theorem as in the annex, but I am obtaining analytically for example for P=5N, a displacement of SD=0.7 mm on D position.
(0.140136x5=0.7 mm)
When experimentally, on the comparator, It obtained a value of displacement of 1.4...
