The shear force at a certain section of a beam is stated to be zero the bending moment at the section will be
Answers
Answer:
either maximum or minimum
Answer:
When shear is zero, the forces are either zero or cancel each other out.
Explanation:
Given that it is the product of force and distance, it provides us with a continuous bending moment. Shear, on the other hand, is the rate of change of the bending moment. Therefore, if there is no change at all, it is either constant or at its highest point.
What does shear force mean?
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 term refers to the ability of such a force to cut through the surface or object that is being stretched. A common example of shear force is a pair of scissors. Only the shear force may cause an object, like a piece of paper, to be cut into two pieces when it is positioned between the two metal blades of a pair of scissors.
Thus, shear force, also known as shearing force, is a force that acts on a body or material (often observed in beam designs) while an internal force acts in the opposite direction.
