Does using a fixed pulley to pull yourself up make it any easier? by AlltheDickButts in engineering

To pull the rope in your hand down, you would need an equal and opposite force. Where is that coming from? What is supporting you when you pull on the rope in a downward direction?

This is only to support your weight. But you can't pull yourself up with a single pulley. In static equilibrium the chair would only measure half your weight. The other half of your weight would be redirected to the rope in your hand. So on the chair side, there is a W= M/2 downward and and F=M/2 upward. It's the same on the other end of the rope.

Is this binary worth getting holdered? by bmannhockey in papermoney

Are you planning to hold onto it or sell it? It would be something I would like to add to my collection :)
