Question

What is the bending moment that produces a convex curvature at a section of a structure?

Answer 1

The bending moment that produces a convex curvature at a section of a structure occurs when the upper section experiences compressive stress and the lower section experiences tensile stress.

Step-by-step explanation:

The bending moment that produces a convex curvature at a section of a structure is when the upper section of the structure experiences compressive stress (compressing) and the lower section experiences tensile stress (stretching). This can be observed when an object bends downward, such as when elite weightlifters temporarily bend iron bars during lifting.

Answer 2

The bending moment that produces a convex curvature at a section of a structure is counterclockwise.

Step-by-step explanation:

When analyzing the bending of a structure, a counterclockwise bending moment creates a convex curvature. This moment induces tension on the upper surface and compression on the lower surface, resulting in the outward bulging characteristic of convex curvature.

In structural engineering, bending moments are crucial for understanding how a structure responds to applied loads. When a counterclockwise bending moment is applied to a section, it causes the upper fibers to experience tension, pulling them apart, while the lower fibers undergo compression, pushing them closer.

This tension-compression interaction leads to the formation of a convex shape at that section.
