Set pulleys are pulleys that hold the drum at 1 position. Although the power needed to lift or transfer an object is no diverse than lifting it with your hands, stationary pulleys enable you to alter the path of the necessary pressure. For case in point, when connected to a bucket that draws water from a properly, a stationary h2o puller permits you to pull the drinking water sideways, lifting the bucket in a much more practical way than pulling it vertically, 1 hand at a time. The excess weight of the bucket is still the same, but it is less difficult to lift.
