I would think in this case being it is soft cheese that both wedges would be engaged. Being that a formula to find mechanical advantage is displacement input over displacement output i think this would hold up. Even if you were to extend the edge beyond the 9.2 mm the width would increase which...
also to be clear mechanical advantage at the 2 points is referring to the blade engagement. so when only the tip is engaged verse the full length of the blade.
that is not part of the wedge system. it does not contribute to displacement. I would not think that would be a way to disprove this. I would think the standard input displace over output displacement average would suffice for MA for this ideal system.
its not so much the length as it is the angle or slope. the steeper the slope the higher the MA. i assume being that the total displacement is covered once the blade is engaged it would be the total length divided by the total width of the blade. At least i think this would be true for a...
please view photo attached to post. I am referring to that the length from tip to second wedge end of the compound divided by the width or horizontal displacement equals the mechanical advantage of the compound blade.
