1. The problem statement, all variables and given/known data Find the Tension in cable winch BD, link to drawing below. http://i960.photobucket.com/albums/ae86/seanrumsby/Prob3-47.jpg 2. Relevant equations The mass fixed to the other end of the pulley is 200 kg. 3. The attempt at a solution I was under the impression that if one side of the pulley pulled down with 1960 N (200 kg * 9.81 ms^-2) then the tension in the winch would be the same as well. Can anyone shed some light on this?
