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
Mpr = ((b*Db^2)/4)*fy --> ((20*40^2)/4)*2
Evaluating ... ...
Mpr = 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
(Calculation completed in 00.004 seconds)

Information on Shape Factor

Shape Factor is the ratio of Plastic Section Modulus to the Elastic section Modulus.Shape Factor of rectangular section is 1.5.More the value of shape factor more it can withstand stress after yielding.
