    Undergrad Flywheel Leg Press Design - How is this being calculated?

    Let's say I have the mass m=2kg. I have the disc radius, let's say r0 = 0.15m. I want to find which would be the force needed by the user to perform the exercise. I will assume, like the paper did, accelerations ranging from 1 to 10m/s². So now I need Rt, but giving I will build this thing, I...

    Undergrad Flywheel Leg Press Design - How is this being calculated?

    Could you clarify a little more? Rt is supossed to be 1'' then, what means, 0.0254 meters ? And R0 is what, the radius of the disc? In this case, 0.3048 and 0.1524, or not? At the end I just want to understand how I will apply the formula to my case, with only one single disc, giving I have the...

    Undergrad Flywheel Leg Press Design - How is this being calculated?

    Ok I find out one issue from the equation I was trying. Ro is the big radius, and not Rt. So: m = 2 * ( 2670N / 4m/s² ) * (0.1524² / 0.3048² ) = 1335 * 0.25 Kg = 333.75 So this is basically 100times the amount of mass that is posted on the table 333.8 vs 3.338. Why is 100 times more? Why would...

    Undergrad Flywheel Leg Press Design - How is this being calculated?

    Hello guys, I'm looking for some help. I'm reading a paper called "On Flywheel Leg Press Design and its Benefits". I'm interested in calculate the forces that a flywheel machine that I'm building (used for gym exercises) will require the user to use it. Following this paper, they start to...
