Toe Resistance using Allowable Load and Safety Factor Solution

Follow our step by step solution on how to calculate Toe Resistance using Allowable Load and Safety Factor?

FIRST Step Consider the formula

Q bu = (P allow \cdot F s) - Q su

Next Step Substitute values of Variables

∴

Q bu = (10kN \cdot 2.8) - 17.77kN

Next Step Convert Units

∴

Q bu = (10000N \cdot 2.8) - 17770N

Next Step Prepare to Evaluate

∴

Q bu = (10000 \cdot 2.8) - 17770

Next Step Evaluate

∴

Q bu = 10230N

LAST Step Convert to Output's Unit

∴

Q bu = 10.23kN
