I have watched tons of tutorials and they have all 21 mechanical Crafters working with three water wheels but when I try it it does not work because of stress or whatever it's called. Is there any other way I can get more rotational power?
Hi there!
For a project I would like to couple a LED into a fiber and move the output of the fiber with a stage to illuminate a sample. I sadly do not know any specific values for bending radii or stress on the fiber, but I would estimate the radius of the fiber to be always larger than 100 mm. The stage would move in X and Y direction in an automated process and is ment to move many ours a day over a distance in the range of 500 mm in X and Y.
Do you think this could work out in principle? How sensitive are optical fibers to mechanical stress in general? Do you know of any literature about this topic?
Thanks a lot in advance!
What does it mean? Fyi:I'm a 16 year old with no knowledge in physics of whatever. I came across the word piezoelectric in my Computer Science class but couldn't truly understand the semantic of this technology despite googling it.
I am a undergrad student trying to learn math and not sure which topic I should focus more on , so asking for an advice.
I am three years into my career and can apply to become a Professional Engineer (P. Eng) after one more. I'm from Ontario, Canada if that makes a difference, but I'm assuming most regulatory requirements would be similar.
Part of being a P Eng is being able to stamp drawings. However, I remember learning that you can only stamp a drawing if you have the knowledge and capacity to ensure it is a solid engineering design.
My job title is 'Mechanical Designer'. I work at an engineering company with the manufacturing facility on site. My job involves creating designs to meet requirements and ensure that the designs are something that our Production crew can manufacture. I am always paired with a Stress Analysis that will evaluate my design and determine any changes required from a stress point of view. I might do basic hand calculations to see if generally it will be sufficient but pretty much the bulk of the 'engineering' part is done by the Stress team.
It would seem to me that because I don't have that in depth analysis knowledge the stress team does, I would not be able to sign off on drawings. I asked one of my electrical engineers co-workers about this (he's the same age), and he said he felt he has all the knowledge required to stamp a drawing. We don't have an electrical 'stress' team so I guess his work covers the whole process of the design from start to finish.
Is my concern normal among MEs?
Are most companies set up with a design/stress team or do most MEs do both design and analysis?
Do you have to be a Stress Analysis to stamp drawings or can other ME branches also stamp?
Any input or advice would be great! Thanks

Actin + myosin are of course big contributors, but what else? I'm having trouble finding reviews that really answer this. Thanks :)
Aka does a ballon stays inflated less long after reuse?
Talking about the type of ballons you use with kids. (Made of latex?)
I know that latex, rubber and plastics have different permeability for different gases, but I am not sure whether this permeability can be affected mechanically.
If so, the common stretching of the uninflated ballon before first use might result in it holding less air.
(Edit) I Keep learning this the hard way. You shouldn’t.
