Tensile Stress in Valve Stem due to Spring Force on Valve Solution

Follow our step by step solution on how to calculate Tensile Stress in Valve Stem due to Spring Force on Valve?

FIRST Step Consider the formula

σ t = 1.4 \cdot \frac{P s}{t^{2}} \cdot (1 - \frac{2 \cdot d s}{3 \cdot d p})

Next Step Substitute values of Variables

∴

σ t = 1.4 \cdot \frac{63N}{{5.5mm}^{2}} \cdot (1 - \frac{2 \cdot 15mm}{3 \cdot 40mm})

Next Step Convert Units

∴

σ t = 1.4 \cdot \frac{63N}{{0.0055m}^{2}} \cdot (1 - \frac{2 \cdot 0.015m}{3 \cdot 0.04m})

Next Step Prepare to Evaluate

∴

σ t = 1.4 \cdot \frac{63}{{0.0055}^{2}} \cdot (1 - \frac{2 \cdot 0.015}{3 \cdot 0.04})

Next Step Evaluate

∴

σ t = 2186776.85950413Pa

Next Step Convert to Output's Unit

∴

σ t = 2.18677685950413N/mm²

LAST Step Rounding Answer

∴

σ t = 2.1868N/mm²
