What is a problem of my graph?(frequency response)

AI Thread Summary
The Bode plot created using MATLAB does not match the one in the referenced paper, specifically regarding the peak location, which is at 10^3 in the paper and 10^4 in the user's graph. The discrepancy is attributed to a potential misunderstanding in the plotting variables, where the user is plotting against angular frequency (ω) while the paper uses frequency (f). This results in a factor of 2π difference between the two plots. Clarification on the correct variable to use is essential for accurate comparison. Ensuring consistent units in frequency response analysis is crucial for valid results.

I have drawn a bode plot(freauency response), but it is not the same with one which is attatched in paper.

Using this data, I have drawn the graph using matlab.

I just put data into second order vibratoion system which is given in the paper(eq 18)

Peak location of graph in paper is just in front of 10^3 but the other is just in front of 10^4.
What is wrong?

I think you are plotting vs ω, and the paper is plotting vs f, so there is a factor of 2π difference.

Thank you.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
