Overall Efficiency of Power Screw Solution

Follow our step by step solution on how to calculate Overall Efficiency of Power Screw?

FIRST Step Consider the formula

η = W a \cdot \frac{L}{2 \cdot π \cdot Mt t}

Next Step Substitute values of Variables

∴

η = 131000N \cdot \frac{11mm}{2 \cdot π \cdot 658700N*mm}

Next Step Substitute values of Constants

∴

η = 131000N \cdot \frac{11mm}{2 \cdot 3.1416 \cdot 658700N*mm}

Next Step Convert Units

∴

η = 131000N \cdot \frac{0.011m}{2 \cdot 3.1416 \cdot 658.7N*m}

Next Step Prepare to Evaluate

∴

η = 131000 \cdot \frac{0.011}{2 \cdot 3.1416 \cdot 658.7}

Next Step Evaluate

∴

η = 0.348174089867043

LAST Step Rounding Answer

∴

η = 0.3482
