    I Mechanical Advantage of a Leveraged Squat Machine?

    Ok, so easiest/best to just compare the work done by the difference in distance the person moves (squat to standing) vs. the distance the weight moves, which is much smaller? As an aside then, (although I didn't carry the calculations all the way through) shouldn't the sequence of calculations...

    I Mechanical Advantage of a Leveraged Squat Machine?

    For assessing the torques and forces in a simplified way... am I headed in the right direction? (Just making up relative lengths, radii, etc.) Or am I completely confused about this calculation process?

    I Mechanical Advantage of a Leveraged Squat Machine?

    Can someone explain how squat machines like these seem to allow people to lift an extraordinary amount of weight (more than they would be able to with free-weights)? Would really appreciate a breakdown of how the force applied by the lifter translates to torque across the levers and gears. Thanks!
