The answer is not formulatic. There will be a parabolic shape from the dead load and a discontinuity at the point load.

Where does the maximum bending moment occur in a simply supported beam?
It depends on the loading conditions of the beam, it will generally occur close to the middle of the span.
Is flexural modulus the same as bending stiffness?
It is related. Flexural modulus is the modulus of elasticity (E) in bending and the higher it is the higher the bending stiffness. Technically, bending stiffness is the product of the flexural modulus and the material bending moment of inertia, I, that is EI.
What is ultimate bending strength?
It is the maximum stress at which a material will fail when subject to flexural ( moment producing) bending loads. These stresses occur a the material outer fibers.
What basics should know the mechanical engineer?
A MECHANICAL ENGINEER SHOULD ALWAYS KNOW THESE THESE FOLLOWING BASICS: NEWTONS LAWS OF MOTION THERMODYNAMICS LAWS STRESS STRIAN DIAGRAM (YOUNG's MODULUS) BENDING MOMENT DIAGRAM PRINCIPLE OF SUSPENSION BRIDGE SOFTWARES LIKE: PRO-E AUTOCAD AND A LITTLE ELECTRONICS AND A LITTLE MANAGEMENT.
What is the relationship between bending and strain?
From the Hooke law, stress s is proportional to strain e; s = Ee where E is elastic modulus of the material; the stress is the bending stress which varies from plus on one surface to minus on the opposite surface.
What are the Bending moment diagram for simply supported beam loaded in its center?
zero
What are the Bending moment diagram for simply supported beam with udl?
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
Where does point of contraflexure occurs?
it occur where moment becomes zero in bending moment diagram.
What is the difference between influence line diagram and bending moment diagram?
in strength of material, u studied shear force and bending moment diagram for static load ( load position is fixed) but influence line diagram is used to draw shear force diagram and bending moment diagram for moving load (load position varies with distance).. Recomended books, CS REDDY & BC PUNMIA.. or email me: parvez.civilengg@gmail.com
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.
What is free body diagram and how to draw shear force and bending moment diagram?
the shear force diagram and the bending moment diagram are two separate diagrams each depicting their respective quantities.shear force and bending moment diagrams are extremely important as these two diagrams give what is needed of the beam that is to be designed. the procedure of sectioning the beam and finding the system of forces at the section is the most fundamental approach. for example the bending moment diagram can show at one glimpse the point of beam which is going to experience the maximum loading conditions and this point can be selected as the minimum requirement of the beam.
Explain in detail about the BMdiagram?
The BM diagram can help you in the calculation of the shear force and the bending moment.
What is the Shape of bending moment diagram for cantilever beam carrying uniformly distributed load?

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 the physical significance of bending moment diagram in structure?
If we use a light weighted material offered no resistance then the beam deflects as per the diagram.
Shear force bending moment diagram?
a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"
Show the diagram of long beam?
Beams are usually long, straight, prismatic members and always subjected forces and bending moment diagram(BMD) of a beam shows the variation of shear.
