i want to do my assignmenyt on air craft structures. the forces acting on wing box root cross section.
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 importance of shear force and bending moment diagram in mechanics lies in structural design and in deflection of beams.
Shear force is the force perpendicular to the axis of an object, causing it to shear or slide. Bending moment is the measure of the bending effect of a force applied to an object, causing it to bend or deform. In essence, shear force is the force that tends to make a body slide or cut, while bending moment is the force that tends to make a body bend.
Cry man, cry!
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.
The bending force is called a moment or bending moment. It is a measure of the internal force at a point in a structure when a bending load is applied.
I also searching for same..
The BM diagram can help you in the calculation of the shear force and the bending moment.
a simple definition " IT'S A COUPLE OF FORCE HAVING EQUAL MAGNITUDE BUT OPPOSITE IN DIRECTION & HAVING VERY LESS DISTANCE BETWEEN THEM"
To determine the internal shear forces and moments at any given point on a rigid body.
To calculate the bending moment of any point:WL/2 x X - WX x X/2W = WeightL = Length of beamX = distance
