WebSep 12, 2024 · There is a pulley system I remember from Compound Machines that use few pulleys to get an arbitrarily high IMA: Differential Pulley. I did a description in the scioly wiki Compound Machine page. There are a few drawbacks though: it is harder to build, requiring the wheel and axle-like structure.

WebApr 4, 2024 · The pulley system is shown in the above figure is a combination of a first-order system and a second-order system as shown in illustrated in the below figures (a) and (b). Let load W be lifted by a distance x. Consider the first-order system portion as shown in figure (a). Here there are two movable pulleys. Hence Velocity Ratio (VR) = 22 = 4 WebThe most commonly understood concept of a pulley is that it is a simple machine that redirects force. This means that by looping rope around a pulley and attaching the rope to an object, one pulls down on the rope to … WebThe equation for IMA is shown in Figure 9.8 (b).
