Plastic Moment for Rectangular Section Solution

STEP 0: Pre-Calculation Summary

Formula Used

Plastic Moment for a Rectangular Section = ((Width of Rectangular Beam*Depth of Rectangle Beam^2)/4)*Yield Stress of a Section
Mp_r = ((b*D_b^2)/4)*fy
This formula uses 4 Variables

Variables Used

Plastic Moment for a Rectangular Section - (Measured in Newton Meter) - Plastic Moment for a Rectangular Section is defined as the moment at which the entire cross section has reached it yield stress.
Width of Rectangular Beam - (Measured in Millimeter) - Width of Rectangular Beam is the cross-section of the beam parallel to the axis in consideration..
Depth of Rectangle Beam - (Measured in Millimeter) - Depth of Rectangle Beam is the overall depth of the cross-section of the beam perpendicular to the axis of the beam.
Yield Stress of a Section - (Measured in Pascal) - Yield Stress of a Section is how much force needs to be applied to a beam to cause it to change from elastic deformation to plastic deformation.

STEP 1: Convert Input(s) to Base Unit

Width of Rectangular Beam: 20 Millimeter --> 20 Millimeter No Conversion Required
Depth of Rectangle Beam: 40 Millimeter --> 40 Millimeter No Conversion Required
Yield Stress of a Section: 2 Newton per Square Meter --> 2 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Mp_r = ((b*D_b^2)/4)*fy --> ((20*40^2)/4)*2

Evaluating ... ...

Mp_r = 16000

STEP 3: Convert Result to Output's Unit

16000 Newton Meter --> No Conversion Required

FINAL ANSWER

16000 Newton Meter <-- Plastic Moment for a Rectangular Section
