Forces on a weight stack with the position of the pulleys so the weight is pulled up and the puller is moving a horizontally. Is it correct to use F=MG?
Without a diagram it's hard to say for sure, but if I'm picturing it correctly, I think the answer is yes.Forces on a weight stack with the position of the pulleys so the weight is pulled up and the puller is moving a horizontally. Is it correct to use F=MG?
The force on the horizontal rope has to support the weight of the object, so your assumption is correct. However, if you start moving the weight up or down, the pulley system has to factor into any other calculations (work, etc.).See attachment :)
