What is the primary purpose of using a shear diagram in beam analysis?

Step 1: Understand that a beam is a structural element that supports loads.
Step 2: Recognize that when loads are applied to a beam, they create internal forces.
Step 3: Identify that one of these internal forces is called shear force, which acts along the length of the beam.
Step 4: Learn that a shear diagram is a graphical representation of how these shear forces change from one end of the beam to the other.
Step 5: Realize that the primary purpose of the shear diagram is to help engineers and designers see where the shear forces are highest and lowest.
Step 6: Conclude that this visualization aids in ensuring the beam is designed safely and effectively to handle the applied loads.
