Correct option is A
A
cantilever beam is a type of beam that is
rigidly fixed at one end while the other end remains
free. It carries loads along its length without any external support at the free end.
Characteristics of a Cantilever Beam:
·
One end is fixed (restraining translation and rotation).
·
The other end is free, allowing deflection and rotation.
· It experiences
bending moment, shear force, and deflection along its length.
· Used in structures like
balconies, overhanging roofs, and bridges.
Cantilever Beam Reactions:
At the
fixed end, there is:
·
A vertical reaction force (shear force).
·
A bending moment (due to applied loads).
·
No horizontal movement or rotation (fixed support resists motion).
