But the same amount of work :)


 define "work"...
the pressure/effort for movement is halved.

work by definition, goes to the point of the source... levers make "work" easier, and reduce the output upon thos supplying the effort.. so.. no, it's less work. Less effort, to accomplish the task.

Correct me if I’m wrong, please. Doesn’t the floating pulley travel half the distance that the cable travels? The effect being that the work is 1/2 of normal.

define "work"..."

Perhaps "energy over time" then.  In any case, for this type of system, "work" and "energy" are the same. "Effort" is a lay term for force, which does not account for time or distance.

Yes, the pressure applied (which is the force or effort) is halved, but not the amount of work.

No.  The work doesn't change.  It is the same amount of work/energy.  You are reducing force/pressure while increasing time/distance.

As I said in a previous post- you can't magically make something use less energy with gears and pulleys- there is a time element involved.  A pulley system can reduce the amount of force, but you have to apply the force for more time/travel.... or in reverse (more force, but in less time/travel).  Energy (or work) is conserved (stays the same).

https://www.explainthatstuff.com/pulleys.html

A simple example would be hauling 10 gallons of water up some stairs.  It is less effort to move a 5 gallon container up the stairs than it would be a 10 gallon container- but you would have to make two trips (you double the distance/time).  So it is the same amount of work (ignoring that you would have to go back down the stairs again :) ).

In the example of a clutch lever- you would be using the same amount of calories (a biological unit of energy/work), your muscles would be doing the same amount of "workout"- either less effort for more time, or more effort for less time.  Pick your poison :)

2 wheeled farm implements have straight cut gears for sure engagement. They don't care about the extra noise when you're bailing hay and ****.

Let's talk about the physics of sharpness...
