**Principal orientations for beam flexure**. This {{:wikiffcd2022:l-section-largerots-hie_rotunitm.gif?linkonly|gif animation}} presents the axial stress component map as a function of the bending moment vector orientation, as evidenced by the rotating needle. | **Principal orientations for beam flexure**.

It clearly appears that, for a generic (vs. e.g. circular) cross section, the neutral axis may significantly deviate from the moment vector orientation; those two directions become parallel only in correspondence of the principal directions for bending (located at [18.4°-18.5°]+N·90° for the cross section under scrutiny). The bending moment rotates of 0.1° each increment. | It clearly appears that, for a generic (vs. e.g. circular) cross section, the neutral axis may significantly deviate from the moment vector orientation; those two directions become parallel only in correspondence of the principal directions for bending (located at [18.4°-18.5°]+N·90° for the cross section under scrutiny).
