As shown in this video, the simulated knee cap creates a fulcrum that allows for a better mechanical advantage for the muscles to pull the leg.
So I was wondering if the reverse would also work, or if it wouldn't change much at all.
For example, in this illustration I made on paint, it is shown a mechanical lever type 3 with 20 cm of length, where the load is on a 20 cm distance from the fulcrum and the effort is at 10 cm distance from the fulcrum and the effort is being done by a rope pulled by a motor.
Accordingly to this online mechanical lever calculator, inputing these numbers would give me 0.5 of mechanical advantage, so in order to lift 1 kg, I would need to input twice the value in order to achieve equilibrium.
However, if I insert a "reverse knee cap" over the effort at the same 10 cm distance and attached the effort rope directly to the point of the load arm, as shown in the illustration, would the mechanical advantage stay the same, or it would change?
