Question

The bending moment (m) is constant over a length segment (i) of a beam. the shearing force will also be constant over this length and is given by

Answer 1

Concept introduction:

Shear force, like the pressure of air flow over an airplane wing, is a force that acts in a direction that is parallel to (over the top of) a surface or cross section of a body. The word "shear" in the phrase refers to the ability of such a force to cut through the surface or item that is being stretched.

Explanation:

Given that, the bending moment (m) is constant over a length segment of a beam.

We have to find, shearing force over its length.

According to the question,

Shear stress is defined as the force exerted on a certain section, F, divided by the section's cross-sectional area, A, computed in the force's direction. For instance, the shear stress is equal to $-F/A$ for a force F acting normal to the surface of a beam with a cross sectional area of A.

Final Answer:

Shearing force is given by $-F/A$.

Answer 2

Answer:

The bending moment (m) is constant over a length segment (i) of a beam. the shearing force will also be constant over this length and is given by $-\frac{F}{A}$

Concept:

Shear force is a force that works in a direction that is parallel to (over the top of) a surface or cross-section of a body, similar to the pressure of airflow over an airplane wing. The ability of such a force to cut through the surface or object that is being stretched is indicated by the word "shear" in the sentence.

Explanation:

• Given that, the bending moment (m) is constant over a long segment of a beam.
• We must determine the shearing force along its length.
• Shear stress is defined as the force applied to a certain section, F, divided by the section's cross-sectional area, A, calculated in the direction of the force. In the case of a force, F applied normally to the surface of a beam with a cross-sectional area of A, the shear stress is equal to $-\frac{F}{A}$
• Shearing force is given by the $-\frac{F}{A}$
