Strength of Butt Welded Joint Solution

Follow our step by step solution on how to calculate Strength of Butt Welded Joint?

FIRST Step Consider the formula

σ t = \frac{P}{b ns \cdot L}

Next Step Substitute values of Variables

∴

σ t = \frac{16.5kN}{15mm \cdot 19.5mm}

Next Step Convert Units

∴

σ t = \frac{16500N}{0.015m \cdot 0.0195m}

Next Step Prepare to Evaluate

∴

σ t = \frac{16500}{0.015 \cdot 0.0195}

Next Step Evaluate

∴

σ t = 56410256.4102564Pa

Next Step Convert to Output's Unit

∴

σ t = 56.4102564102564N/mm²

LAST Step Rounding Answer

∴

σ t = 56.4103N/mm²
