There are two ways to draw the shear and moment diagrams. First is by writing the shear and moment equations and the other which is more rapid is by using the relationship between load, shear, and moment. For any of the two methods, the first step is to find the reactions at the support(s).
Shear and moment diagram by writing the shear and moment equations
Cut the beam in every segment where there is a change of load. Draw the free body diagram to the left of each exploratory section. Write the shear and moment equations and with these equations, you can easily draw the shear and moment diagrams. For examples and the detailed step by step step instruction on how to do this can be found by the link below:
Using the relationship of load, shear, and moment
Drawing the shear and moment diagrams by using the relationship between load, shear, and moment is more rapid than writing the shear and moment equations. The relationship are as follows:
- The slope of shear = Load
- Slope of Moment = Shear
- Area of load = shear of a segment
- Area of shear = moment of a segment

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 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)..

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 absolute maximum bending moment in influence line diagram?
The absolute maximum bending moment in an influence line diagram represents the greatest bending moment that can occur at a specific location in a structural member due to a moving load. This moment is determined by analyzing the influence line, which illustrates how the bending moment varies as a point load moves across the structure. The peak value of the bending moment on the influence line indicates the worst-case scenario for design and safety considerations. It is essential for engineers to calculate this value to ensure structural integrity under varying load conditions.
How do you calculate point of contraflexure?
The point of contraflexure in a beam is where the bending moment changes sign, indicating a shift from positive to negative bending moments or vice versa. To calculate it, you first need to determine the bending moment diagram for the beam under the given loads. The points of contraflexure occur where the bending moment is zero; you can find these points by solving the bending moment equation derived from the beam's loading conditions and boundary conditions. Set the bending moment equation equal to zero and solve for the position along the beam.

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.
