[quote=MN3][quote]Doesn't the straight aft pull exert the most leverage on the base of the winch post?[/quote]
i am not an engineer (nor trying to be argumentative) i would [b]hypothesize [/b]the higher the winch is up the post changes the location of the effort / strain
I.E. ceteris paribus...
if you have a 6' post and place the winch (or block) at the very top the post will fail (bend) in the middle
if you have a 6' post and place the winch (or block) at the base of post the post will fail at the base (or attachment point)
assuming 3' is "straight aft"it will fail in the middle (1.5')
you stated that "heavy boats are pulled up the trailer via a winch on a post"... That's a floating boat... doesn't matter how much the boat weighs (to a point) if it is floating...
no one is pulling a powerboat up a beach or onto a trailer using a hand winch<!-- editby --><em>Edited by MN3 on Oct 04, 2016 - 03:59 PM.</em><!-- end editby --> [/quote]
