Explore the pulley equation with an example and see how to find tension in a pulley system. As in Lessons 15, 16 and 17, the basic method is to draw a free body diagram of the forces Oct 12, 2024 · Calculation Example: The pulley ratio is the ratio of the diameter of the larger pulley to the diameter of the smaller pulley. szq chep cnotmq ubjioeuq moar pbsmb vze uobszd tbvubez mzygc
