My first Video

No I,m not.

If the section has accelerated, which it has if it is falling it now has converted its potential energy to kinetic being accelerated @9.8m/s/s

This increased kinetic energy has to go somewhere which you are trying reduce by the friction device.

The friction device turns some of the kinetic energy to heat energy( feel your portawrap next time)

If the section is being slowed earlier by rope and not falling, the kinetic energy value will be smaller as it has been decelerating sooner so the forces are lower.

 

Thats been on the tip of my tongue all night!!

It still doesn't matter, the increased energy is just dispersed over a longer distance so equaling the smaller force over a shorter distance

Watch your fingers in that gob cut Marc

Just watched it again. I just spent today lowering with the exact same pulley that Mike was using. Since when can't you use one of them??

 

I have a large pulley for really heavy stuff but why lug that into the tree if you're only lowering small stuff?

[tommer9]

how long have you been cutting and climbing blakes:001_smile:

 

Bump. I would love to know too.

snap. i have to be rigging real big stuff before the blocks come out.....mikes rigging was relatively light, particularly with how well the pieces were being controlled
