If the crate weighs Transcribed image text: = = A person uses a rope/pulley system (i.e. block and tackle) to hold a large crate steady on an incline, as shown in the diagram below. The crate weighs 183 lbs, and it has dimensions of b = 3 ft and h = 6 ft. The incline is at an angle of 30 degrees from the horizontal plane, and the static coefficient of friction between the surfaces of the crate and the incline is ...

The IMA of a block and tackle can be determined by the number of times a rope passes through the lifting pulley wheels system. One pulley equals one advantage, two pulleys equal two, and so on. In other words, if you want to lift a 100-pound weight, a one-pulley system would still equal 100 pounds.
