    I want to know all of the maths concerning this scissor mechanism!

    so I worked out that 3.392920066J / 0.126 = 26.92793703N at the cam

    I want to know all of the maths concerning this scissor mechanism!

    so I have seen this pdf before and stated a while ago that the point of application of the force is not included in the document there is some that come close and I bet someone on here can utilise the equations in that document and modify for my application but my maths is not up to scratch...

    I want to know all of the maths concerning this scissor mechanism!

    I think that that is my point 2.7N * 1.26 = 3.39J but if you take the 2.7N at the bottom of the scissor with force 2.7N and it moves 0.126m that equals 0.3402J!!

    I want to know all of the maths concerning this scissor mechanism!

    because my intuition says somethings up, bassically I don't know, it would be harder to lift up that way, through the scissor than lifting it strait because you're decreasing the distance moved by a factor of 10 (the point at which the cam touches) in the same time it takes to move the weight...

    I want to know all of the maths concerning this scissor mechanism!

    ok so back to the scissor mechanism, I have been giving this some thought, while I agree that at any given height of the blue circle at a stationary instant, you would feel the weight of the block at the top and nothing more at standstill rejecting mass of scissor, but when you go to lift the...

    Sallen Key Low Pass Filter, bandpass filter

    lost momentum with this project kind of lost motivation to finish it I'll get back to it soon and have a proper update!!

    I want to know all of the maths concerning this scissor mechanism!

    so what I need to do right now is to create a freewheel mechanism any suggestions people??

    I want to know all of the maths concerning this scissor mechanism!

    so did one more calculation with the outer radius of 0.55m and the inner radius of 0.5m the weight of the flywheel equals 39.095kg and that yields a thickness of 95mm so I think that will be the closest to the 100mm thickness I was after! now putting into solidworks!

    I want to know all of the maths concerning this scissor mechanism!

    im thinking if I do the inertia 10.8 / (Ri + Ro)^2 that might give me the mass, then I might be able to work out the thickness of the ring with volume and density! is this line of thinking correct??? or could it be 10.8 / 0.5 * (Ri + Ro)^2 for mass edit: so I found out that I = 1/2 * M * (Ri^2...

    I want to know all of the maths concerning this scissor mechanism!

    maybe you might be able to understand it and give it a crack on my behalf chat gpt is just giving me ridiculus figures! :)

    I want to know all of the maths concerning this scissor mechanism!

    I want to design a flywheel ring type and its inertia needs to be 10.8kgm^2 and the thickness should be 80mm to 100mm, also the hub is 100mm in diameter with a hole for a shaft equal to 35mm and should be 150mm thick in depth, the spokes go from the hub to the ring there will be 3 spokes and...

    I want to know all of the maths concerning this scissor mechanism!

    perhaps if a ring is just mr^2 then inertia10.8/ radius0.5 = mass =21.6kg but then that still needs the inner and outer edges and thickness plus I'm not too good with calculus there must be an easier way to calculate!! thanks though

    I want to know all of the maths concerning this scissor mechanism!

    ok cool thats good how do I relate it to the desired moment of inertia of 10.8kgm^2? thanks by the way It doesnt HAVE to be 60kg although would like it to be I want it to be 100mm thick Ra 0.5m outer density 7850 need to work out inner diameter and weight to satisfy the inertia of 10.8kgm^2 I...

    ok so do you want to help?
  20. Maglatron

    I want to ask a few questions. Can I control a 380 DC motor using Arduino with a driver card? And I want to ask another question. Can I calculate the

    hahaha that is ace man haha fantastic lol
