Calculate The Nominal Moment Capacity Of A Beam Section:
(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)
Area of steel (As - sq in or sq cm)
Depth to steel reinforcement (d - in or cm)
Steel yield strength (fy - psi or kPa)
Distance from centroid to extreme compression fiber (dc - in or cm)
