Question

The bending which a beam or girder undergoes from its own weight or by reason of a load is referred to as ____________?

Answer 1

The bending which a beam or girder undergoes from its own weight or by reason of a load is referred to as flexural or bending stress. When a beam or girder is subjected to a load, the top surface is compressed and the bottom surface is stretched, resulting in a combination of compressive and tensile stresses. For example, a long shelf loaded with heavy books sags between the end supports due to the weight of the books.

Step-by-step explanation:

The bending which a beam or girder undergoes from its own weight or by reason of a load is referred to as flexural or bending stress.

When a beam or girder is subjected to a load, the top surface is compressed and the bottom surface is stretched, resulting in a combination of compressive and tensile stresses. This stress distribution causes the beam to bend or sag.

For example, a long shelf loaded with heavy books sags between the end supports due to the weight of the books. The top surface of the shelf is in compressive stress, while the bottom surface is in tensile stress.
