does anybody has any websites or relevant material on how to draw the shear force and bending moment diagram??
pls help...
thanx

Shear force and bending moment are two important factors in the analysis of structural mechanics. They refer to the internal forces and moments that act on a structure, causing it to deform or fail under loading. Shear force is the force that acts parallel to the cross-section of a structure, while bending moment is the measure of the rotational force required to bend a structure.
Shear force and bending moment can be calculated using the principles of statics and mechanics of materials. Shear force is calculated by summing the forces acting on a structure in a specific direction, while bending moment is calculated by summing the moments of the forces acting on a structure about a specific point. Both calculations involve the use of free body diagrams and equations of equilibrium.
Shear force and bending moment are important parameters in the design of structures because they determine the strength and stability of a structure. By analyzing and understanding the distribution of shear force and bending moment along a structure, engineers can determine the appropriate materials, dimensions, and reinforcement needed to ensure the structural integrity and safety of a building or other structure.
The effects of shear force and bending moment on a structure depend on the type of structure and its load-bearing system. For example, in a beam, shear force and bending moment can cause deflection and stress, while in a column, they can cause buckling. In a truss structure, shear force and bending moment are distributed among multiple members, while in a frame structure, they are resisted by the entire system.
Yes, shear force and bending moment can be controlled or minimized through careful design and consideration of the loading conditions and structural elements. For example, the use of stronger materials, increasing the depth or width of a beam, or adding additional supports can help reduce the effects of shear force and bending moment. Advanced structural analysis and design techniques can also be used to optimize the distribution of these forces within a structure.
