Does anyone else make a distinction between mechanical advantage and leverage?
i've always thought of leverage as an increase in output compared to input from a common machine link / point. But, rotatonally/ non-inline applied. Like a lever or sweating a line; maximum force ratio at perpendicular; direction constantly changing; to alter distance/force ratio from given power source geometerically; with multiplier by angle.
Mechanical Advantage; i think of more in the pulley sense; inline force to alter distance/force ratio from given power source. Input/output on same axis; direction not changing; most power at inline input to output. Also, the increases are an additive/ arthmetic per sheave in a system (multiplying between systems). Even though a pulley itself is rotational; it is by itself a 1:1 1st class lever. If following other leverage descriptions a pulley in a system determines it's advantage by the pulley's position in 3 available places. On input as 3rd class lever for 1:2, on output as 2nd class for 2:1 and on linking machine as 1stclass for 1:1. But this rolling lever thing is another thing i kinda don't like; in that to me, leverage should imply a constant change in direction(?).
i guess the final hair splitting is we leverage non-flexables; with angular/non-inline force. Inline force gives non-flexable; no advantage without impact(?). And flexable doesn't resist bending, so has no resistance to angular/non-inline force so we take another leg of inline pull for advantage. But, sweating a tight line, takes the flexable line and makes it resist bending to get the rotational leverage with angular force. So, i think of pulley as MA and sweating as leverage, multiplying and changing direction on output(?).
Am i alone (again)?
