Why you study about shear force and bending moment?
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
Why would bridge engineers choose a arch bridge design over other bridge designs?
Becuase bending moment in the middle of the bridge bending moment is less than ordinary or straight bridge and more strength
What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
Why is the maximum bending moment of a structural member as the point of zero shear?
Shear is the rate at which bending moment changes or shear is its derivative with respect to span. The integral, bending moment, goes through a maximum when shear goes from positive to negative or vice-versa.
Where does point of contraflexure occurs?
it occur where moment becomes zero in bending moment diagram.
What is a bending moment envelope?
A moment envelope defines the extreme boundary value of moment along the beam due to critical placements of design live load.
What is the impotence of bending moment in beams?
to know the how much moment it can bear . and design purpose

What is the difference between deflection and bending?
Bending moment With "bending" you really mean the bending moment. The bending moment in an inner stress within a member (usually beam) that allows it to carry a load. The bending moment doesn't say anything about how much a beam would actually bend (deflect). Deflection Deflection measures the actual change in a material you could call "bending." It measures the physical displacement of a member under a load.
What will be the shear force when bending moment is constant?
On SFD's and BMD's: The shear force will be 0, the shear force is the derivative of the bending moment at a point on shear force and bending moment diagrams. Otherwise: It depends on the loading.
What is bending moment?
bending force is the amount of energy it takes to compromise the item from its natural shape or conditionA bending force is a combination of tension and compression.
What is point of contraflecture?
The term "point of contraflexure" is often used in structural engineering, specifically in the context of analyzing and designing beams subjected to bending loads. In simple terms, the point of contraflexure is the location along the length of a beam where the bending moment is zero. When a beam is subjected to bending loads, it experiences tensile (positive) bending moments and compressive (negative) bending moments along its length. The bending moment varies along the beam, reaching a maximum at the points where the bending is the most significant. These points are usually located near the supports of the beam. However, in some cases, particularly in continuous beams or beams with complex loading conditions, there may be a section along the beam where the bending moment changes direction from positive to negative or vice versa. This section is known as the point of contraflexure. At the point of contraflexure, the bending moment is zero, and the beam's curvature changes direction. This point is essential in the analysis and design of structures as it affects the internal forces and stresses within the beam. Identifying the point of contraflexure is crucial for engineers to ensure the beam's stability and design it appropriately to handle the bending loads effectively. The bending moment diagram is used to visualize the variation of bending moments along the length of the beam and to locate the point of contraflexure if it exists.
What is a bending moment in applied mechanics?
Its
What is difference between moment and bending moment?
Take a beam as an example. Moment is responsible for a beam to rotate about some axis. Whereas bending moment are a pair of moments which will not rotate the beam but it will deflect it.
