a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"
shear force will be nil when bending moment is maximum
bending moment in columnsatL/2 maximum and atL/4 minimum. Laps must be below the L/4 at both end.
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
It is parabolic, or second order:M = q x squared/2An excellent software to view the profiles of Shear force & Bending moment diagrams.http://www.mdsolids.com/
To calculate the bending moment of any point:WL/2 x X - WX x X/2W = WeightL = Length of beamX = distance
The importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
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.
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
The BM diagram can help you in the calculation of the shear force and the bending moment.
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
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.
Shear Force: Sum of all Vertical Forces Whose acting on a Beam but Sum of all vertical Forces must be equal to Zero. Bending Moment: The Product of Force And Displacement is known as Bending moment.
Parabolic, max moment at midspan of value wL^2/8 where w is the distributed load and L the length of the beam.
0, bending moment is at maximum
