Hey! Thanks for the help, really. I all humbled by you guys.
The time it takes to charge it is not really important application wise because once I release that charge, i will only need it again in about 1 min or more. But from the equations isn't the discharge time somewhat related to the...
Thanks! In Choosing a Capacitor I tried some initial computations and have come up with using a 300uF Capacitor with a 2 Ohm Resistor with an initial voltage supply of 20V. (Its really going to be 5V but for the sake of computing a capacitor I used 20V).
If i`m right this will give the...
Hey, the magnet assembly is not an electromagnet but an electro permanent magnet. Here is the paper title, you might find it interesting: Electropermanent Magnetic Connectors and Actuators: Devices and Their Application in Programmable Matter
Hi Phyzguy!
At first I was thinking of using just a simple DC-DC Boost converter with a Inductor and a PWM signal from the Micro Controller (Arduino). But now I don't think I can do that because of the 10Amp requirement. I plan to source the power from a typical lithium ion battery which is...
The device is an electropermanent magnet. To switch it `on and off`, I need to run a coil with that power and it only takes a switching time of around that interval.
I`m really a beginner when it comes to designing electrical circuits and only have the ability to replicate cicuit designs. I have no idea how to choose and power up a capacitor the way I want it.
So what I need is a capacitor than I can charge up using a low voltage (around 5V) that can then...
Got it!
I think I finally got it right.
Assuming impulse is the same for both cases and the mass and gravity do not affect impulse at all.
So the relation is*
Am I right?
Okay so, sorry i`m really having a hard time here.
Can you verify if this is correct? Based on what you said... And if it is, I still don`t get the derivation.
I thought as much if it were the same mass yeah, any idea on how to factor in different masses of the objects? Using the equation above would require me to Solve for the Spring`s potential energy which in my case is... kind of hard since it`s not a conventional spring. Is there a more...
Hi, A.T.!
Thank you for your reply and pointing the thread out to me. Learned a lot about the duration the force is applied. The only most important information to my experiment that helped me understand my problem was:
In reality, my experiment is not a finger pushing but a spring of some...
So I'm working on an experiment where I do a projectile motion simulation here on Earth and want to know how it will fair in a low gravity environment such as in the moon with one common parameter in between, Force.
Imagine, here on earth, I have a mass that I push up with a force(F) for it to...
Hey,
So I`ve been trying to wrap my mind on how to solve this problem. I`m trying to use a CFRP Sheet as sort of a spring actuator by using it`s buckling phenomena to deliver a force to the body it`s attached to. Kind of vague so here is a video:
This video does it electrically, but I...
