Current Topic:
PULLEY STUFF

HI ALL:  I should know this because I worked with it a long time ago.  but I have forgotten.  Here is the question.

A vertical hydraulic cylinder with the base fixed has a pulley at the end of the rod.  A rope around the pulley is fixed on one side and has a load, say 100# on the other, or free, side.  Because of this arrangement the force in the rope is 100#, The force on tha rope anchor is 100#, and the force on the hydraulic cylinder is 200#.  The question is:  If the hydrualic cylinder moves up by 2 inches.  How far up does the load on the free end of the rope move?

Thanks

Dave
