How much does the weight divide when a pully is used?

I am going this weekend to the Home Depot to get a pulley to mount to the top of my closet doorway so I can do OTS and different angles. Does’nt the weight divide by the amount of pulleys. And what is the formula??

As long as you only use one pulley you are 1:1 ratio. In other words, from a dead weight perspective, nothing is changed and all weight will be applied. If you use more than one pulley then all bets are off and the weight is cut depending on the amounts used and so forth.

Good idea..

I wonder what BIB used when he did OTS, etc. Did he ever speak of a pulley system or did he just through it over his shoulder….

BIB you out there???

Dash is correct. The only thing you have to worry about is friction. The thing is, use the weight that is correct for you at any certain angle, at a certain time. Even if there are friction losses, they should be constant.

bbs,

OTS, I cut out a piece of 6 inch PVC pipe, about a half moon to put over the back of my office chair. I ground channels in it in order to hold the rope. It is about 1/4-3/8 inch thick. There was some friction, but by working the abs, you can get almost any amount of stress you want.

so the cord holding the weight would be literaly touching your shoulder??

Seems like it could dig into the skin…Also is your back flush against the chair in this position? So your penis is pulled directly against your abdomen right?

No, I slide down in the chair just a little and the top back of the chair takes the weight. It is an executive type office chair with a high back.

Right.

Johnnygate, in an ideal situaion the 1.1 raio may be correct. However, if you want o know precisely you will need a scale to measure. I’ve used a pulley before to hang and the amount of weight hung static versus pulled enough to move weight up can vary sigificantly. Unless you’ve got one hell of a good pulley, check with a scale. Do this for both verification as well as safety sake. X amount of weight can be fine until one shifts postion a bit, then X becomes ouch when the real weight is felt. Pulleys are tricky like that, almost as if some of the cheaper ones have a “start up inertia” that works both ways. Start low and know your pulley. groa
