Calculate second moment of area: Rectangle I = bh³/12, Circle I = πd⁴/64, I-beam I ≈ (BH³ − bh³)/12. Apply parallel axis theorem I = I_centroid + Ad². Compute section modulus S = I/c.
2D stress state at a point. All stresses in MPa.
Enter the values for the patient or scenario you are assessing. Calculate second moment of area: Rectangle I = bh³/12, Circle I = πd⁴/64, I-beam I ≈ (BH³ − bh³)/12. Apply parallel axis theorem I = I_centroid + Ad². Compute section modulus S = I/c. Use the moment of inertia result to inform your clinical assessment.
