Power Absorbed by Disc Brake Solution

Follow our step by step solution on how to calculate Power Absorbed by Disc Brake?

FIRST Step Consider the formula

P d = 2 \cdot p \cdot A p \cdot μ p \cdot R m \cdot n \cdot 2 \cdot n \cdot \frac{N}{60}

Next Step Substitute values of Variables

∴

P d = 2 \cdot 8N/m² \cdot 0.01m² \cdot 0.34 \cdot 0.25m \cdot 2.01 \cdot 2 \cdot 2.01 \cdot \frac{2001/min}{60}

Next Step Convert Units

∴

P d = 2 \cdot 8Pa \cdot 0.01m² \cdot 0.34 \cdot 0.25m \cdot 2.01 \cdot 2 \cdot 2.01 \cdot \frac{3.33331/s}{60}

Next Step Prepare to Evaluate

∴

P d = 2 \cdot 8 \cdot 0.01 \cdot 0.34 \cdot 0.25 \cdot 2.01 \cdot 2 \cdot 2.01 \cdot \frac{3.3333}{60}

Next Step Evaluate

∴

P d = 0.00610503999999999W

LAST Step Rounding Answer

∴

P d = 0.0061W
