to the human at the end of the blocks: (ceteris paribus)
you can sheet all day and feel less muscle fatigue than if you had a lesser purchase system
and expend less Joules (1 kg*(m/s)^2) to hold a sheeted mainsheet in the same position over any length of time[/quote]
See it this way:
Do you feel less hungry at the end of the day? No, because you haven't spent less joules.
Your muscles feel different? Yes, because you applied less Newtons.
equal need of beer will verify that the experiment was ceteris paribus.[/quote]
