Absolute Value of Moment at Quarter Point of Unbraced Beam Segment Solution

Follow our step by step solution on how to calculate Absolute Value of Moment at Quarter Point of Unbraced Beam Segment?

FIRST Step Consider the formula

M A = \frac{(12.5 \cdot M'max) - (2.5 \cdot M'max + 4 \cdot M B + 3 \cdot M C)}{3}

Next Step Substitute values of Variables

∴

M A = \frac{(12.5 \cdot 50.01N*m) - (2.5 \cdot 50.01N*m + 4 \cdot 50.02N*m + 3 \cdot 20.01N*m)}{3}

Next Step Prepare to Evaluate

∴

M A = \frac{(12.5 \cdot 50.01) - (2.5 \cdot 50.01 + 4 \cdot 50.02 + 3 \cdot 20.01)}{3}

Next Step Evaluate

∴

M A = 79.9966666666667N*m

LAST Step Rounding Answer

∴

M A = 79.9967N*m
