Question:medium

Two beams of equal cross sectional areas are subjected to equal bending moment. If one beam has square cross section and the other has circular section, then

Show Hint

For a given cross-sectional area, material distributed further from the neutral axis increases the moment of inertia and section modulus.
A square section distributes its corners further away from the neutral axis than a circular section, making it more efficient in bending.
