Homework Statement
For the pictured block and tackle system, formulate an equation to solve for the rotational speed of each sheave wheel for a given line pull speed. (ignore friction, slippage, line stretch) (Mass, force, efficiency, mechanical advantage are not the focus of this. Pulley speeds are desired for bearing fault detection by frequency spectrum analysis)
Homework Equations
All pulley sheave diameters are same.
The Attempt at a Solution
Numbering sheave from draw line toward fixed rope anchor, I know 1 rotates fastest and 4 rotates slowest, but I can't determine the reduction % at each wheel.
