Diameter of Small Pulley given Wrap Angle of Big Pulley Solution

Follow our step by step solution on how to calculate Diameter of Small Pulley given Wrap Angle of Big Pulley?

FIRST Step Consider the formula

d = D - (2 \cdot C \cdot \sin (\frac{α b - 3.14}{2}))

Next Step Substitute values of Variables

∴

d = 810mm - (2 \cdot 1600mm \cdot \sin (\frac{200° - 3.14}{2}))

Next Step Convert Units

∴

d = 0.81m - (2 \cdot 1.6m \cdot \sin (\frac{3.4907rad - 3.14}{2}))

Next Step Prepare to Evaluate

∴

d = 0.81 - (2 \cdot 1.6 \cdot \sin (\frac{3.4907 - 3.14}{2}))

Next Step Evaluate

∴

d = 0.251816475753736m

Next Step Convert to Output's Unit

∴

d = 251.816475753736mm

LAST Step Rounding Answer

∴

d = 251.8165mm
