### How to Measure Sheave Diameter Sciencing

Apr 25 2017 · Sheaves the circular parts of pulleys carry a belt around a shaft. The belt transmits power to or from one or more other shafts. Knowing the diameter of a sheave matters because a shaft s speed will vary according to its sheave s diameter -- in one rotation a larger sheave will carry a greater length of belt so the shaft turns more slowly.
