Hello everyone,
First off, i would like to apologize for any spelling errors. I am Portuguese and my english is going to be very simple.
I am in the process of building something and i am reaching out to the physics community for help solving a problem.
I am a CNC programmer and while i was in one of my classes in school (Pneumatics) the teacher spoke to us about the principal behind a "Pneumatic Jack" and an "Air Check Valve".
Basically, the valve makes it possible for a human being to lift a car with just the strength of his arms.
This gave me an idea...and a problem to solve.
How do i control the weight of an object?
I need to be able to choose the weight that the object will have with just the turn of a button.
Think of a sphere...it has a button on the side, it's inicial weight is "2 pounds", but if i turn the button to "5", the weight is now "5 pounds".
I've been looking for maybe an element with expending mass, maybe the combination of two elements, where one affects the composition of the other, causing it's mass to expande, but i also need it to retract to it's original weight with another turn of the button to "2".
.
Maybe something in the fields of magnetic forces or electrical current?
I am neither a physicist nor a chemist so this is just me rambling.
This is a question a leave to you if you'll accept the challenge.
Again, sorry for my english, i hope i got the idea across.
Thank you for your attention, and i would really appreciate any feedback.
Take care.
