explanation
This image demonstrates how the orientation and depth of a beam significantly influence its resistance to bending. In the top section, a heavy load (represented by an elephant) is placed on two beams: one remains straight while the other deflects noticeably. The difference occurs because the stiffer beam has greater vertical depth, which increases its moment of inertia and bending resistance. In the lower section, rectangular cross-sections labeled b (width) and h (height) illustrate that when the height is positioned vertically, the beam becomes much stronger and deflects less. When the same section is rotated so the smaller dimension acts as the height, the beam bends more under the same load. This highlights the importance of beam depth in structural performance
