Shear Force and Bending Moment Diagrams for a Cantilevered Beam having UDL + Point Load
A cantilevered beam is a type of beam that is fixed at one end and free at the other. It is commonly used in structures like balconies, bridges, and overhanging roofs. When loads are applied to this beam—like point loads or a uniformly distributed load (UDL)—they cause internal forces in the beam. These internal forces…
Shear Force and Bending Moment Diagrams of Simply Supported Beam having UDL + Point Load
Understanding how forces act inside a beam plays a crucial role in structural engineering. Beams support many structures such as buildings, bridges, and homes. When loads press down on a beam, internal forces, mainly shear forces and bending moments develop to show how the beam will respond. Without knowing these forces, beams could fail, which…
Shear Force and Bending Moment Diagrams of Cantilevered Beam having UDL/VDL
Understanding how cantilevered beams work under different loads is important in structural engineering. A cantilevered beam is fixed at one end and free at the other.
