Just searching around google, would a fishing reel work as my spooling mechanism? It has a reel already attached and perhaps the drag can be used to maintain tension and once the tension is achieved it let's out line and if too much tension persists to build up perhaps the constant force spring...
Alright I am trying to measure the "instantaneous" velocity of a swimmer at around 400Hz.
I plan on attaching the swimmer to some nylon rope or something similar and having the rope go into a "box" that will use pulleys, a wheel mounted to a shaft and shaft encoder that will rotate freely...
Would an instrument amplifier with a setup such as the one posted in another PF topic work?
I suppose it is called a voltage difference amplifier. I suppose I could have one input voltage be my load cell output and have a 2nd power source of 5V which would give me an output of Vo = 0.65*A...
Howdy,
I am a mechanical engineering student with limited circuitry knowledge to start...
Anyhow I have a [-500,+500]lbf load cell that is essentially a wheatstone bridge strain gauge. I want to give it either 9Vdc or 12Vdc excitation voltage since I have a regulated power supply that can...
I am interested in measuring the velocity of a competitive swimmer who is moving linearly across the surface of the pool (and at the beginning of the length to be swum the swimmer would be around 3ft underwater).
The swimmer's velocity is typically between 0.8m/s at the lowest end and up to...
I would imagine this topic is getting into theoretical physics than what is known and used everyday. I sure do not know anything about it, but it is interesting to ponder.
Unfortunately without anyone being able to do it there is nothing to be known about it hah. All theory and from what...
It's definitely sounding like a good idea to get my phd in somthin other than physics first.
Heh I suppose now its just finding out which one I really like most. I'm kinda getting the feeling ima be changing my mind lots before I know...
Is it rare to find research jobs because that...
So since you say that. Are there any readily available jobs that would be applicable with having this kind of degree?
And as for Engineering Physics I'm not hearing much about it period? Including what the job oppertunities are and such. Supposedly it is more applicable since there is more...
Yea it's almost deadline time to pick a college for me... Picking a college that has a good program seams important. And I'm not too sure what major would be best to pursue. I have thought about various Engineering degrees but mostly Engineering Physics or just Physics, but I'm not too sure what...
Well next time I'll remember to go grab a $.99 big bottle of Vess Cream Soda. And use it :smile: . But till then i guess ill sell a few of these to make back the $30 I paid for PVC pipe .
Another odd question but ever use pvc threaded caps? can they withstand pressure or are they vaunerable...
Yes, I'm new here so forgive me if I am in the wrong forums. I am currently assembling a submergable underwater camcorder housing of 6" diameter pvc pipe. I was wondering what is the diference between plexiglass and double strength plexiglass concerning the pressure it can withstand.
I am...
:rolleyes: Recently I have gained great interst on understanding how I gain speed and move through water while swimming in a race. Using the Freestyle as example I have my body in the water creating drag forces or a form of friction. And I must use my hands and feet(mostly hands/arms) to create...
