A simple beam is defined by how it is supported. How is a simple beam characterized?

A simple beam is characterized by being supported at both ends. This configuration allows the beam to experience bending when subjected to loads applied along its length. The supports at both ends permit rotation and vertical movement of the beam, leading to a response primarily characterized by bending moments about its span.

In contrast to other support types, such as being fixed at both ends or supported at just one end, a simple beam's behavior is defined by these end supports which enable a more straightforward analysis of stresses and deflections when loads are applied. This method of support is commonly used in various engineering applications, making the understanding of simple beams essential for students studying structural engineering principles.
