HOW TO DETERMINE SFD AND BMD OF CANTILEVER BEAM CARRYING A POINT LOAD AT FREE END

Hi All,

Please watch my latest video titled “HOW TO DETERMINE SFD AND BMD OF CANTILEVER BEAM“.

In this video i have described what is SFD and BMD of Cantilever beam which is carrying a point load at its free end. I have explained how to find them. The method has been explained further by  taking a numerical problem.

SFD stands for Shear force diagram. It can be made from the loading diagram of the cantilever beam. To draw this diagram , we have to find out the reactions. Then the vertical components of forces and reactions are added one after another from the left end of the beam using sign conventions .

The shear at a section is always equal to the sum of all the vertical forces to the left of the section.

In using the sum procedure, the shear force diagram should give the shear (reaction at right end of the beam) which was calculated earlier, at the end. There is no shear force beyond the last vertical force or reaction. In this way, we can check our mathematical calculations.

BMD stands for Bending Moment Diagram. To draw the bending moment diagram, we move continuously along the length of beam from the left hand end and add the areas of shear force diagrams considering sign conventions. The process of obtaining the moment diagram from the shear force diagram by addition is similar to the process for drawing shear force diagram from load diagram.
