Bending Stress in Arm of Belt Driven Pulley Solution

Follow our step by step solution on how to calculate Bending Stress in Arm of Belt Driven Pulley?

FIRST Step Consider the formula

σ b = M b \cdot \frac{a}{I}

Next Step Substitute values of Variables

∴

σ b = 34500N*mm \cdot \frac{13.66mm}{17350mm⁴}

Next Step Convert Units

∴

σ b = 34.5N*m \cdot \frac{0.0137m}{1.7E-8m⁴}

Next Step Prepare to Evaluate

∴

σ b = 34.5 \cdot \frac{0.0137}{1.7E-8}

Next Step Evaluate

∴

σ b = 27162536.0230548Pa

Next Step Convert to Output's Unit

∴

σ b = 27.1625360230548N/mm²

LAST Step Rounding Answer

∴

σ b = 27.1625N/mm²
