in case (a) there's a downwards force equal to f(g) and a upward force of T (cord tension) on the bosun's chair since it is connected to a rope. But since the man's hands are also "attached" to the rope, there is another upwards of force of T making the sum of upwards forces 2T. (my...

That is also what I meant, poorly formulated by me. Thanks for the replies, much appreciated.

As such: http://puu.sh/14Ya6 ? if yes; to continue with that line of thinking, if one was to picture an imaginary box around the co-worker standing on the ground below him, only one strand extends from that box, thus T = 1?

Homework Statement A man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. the combined mass of the man and chair is 103.0 kg. With what force magnitude must the man pull on the rope if he is to rise...
