Wrap Angle for Big Pulley Solution

Follow our step by step solution on how to calculate Wrap Angle for Big Pulley?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

α b = 3.14 + (2 \cdot (a \sin (\frac{810mm - 270mm}{2 \cdot 1600mm})))

Next Step Convert Units

∴

α b = 3.14 + (2 \cdot (a \sin (\frac{0.81m - 0.27m}{2 \cdot 1.6m})))

Next Step Prepare to Evaluate

∴

α b = 3.14 + (2 \cdot (a \sin (\frac{0.81 - 0.27}{2 \cdot 1.6})))

Next Step Evaluate

∴

α b = 3.47912268773137rad

Next Step Convert to Output's Unit

∴

α b = 199.339046415256°

LAST Step Rounding Answer

∴

α b = 199.339°
