What is a beam supported at its both ends?
The beam that is supported at its both ends it is called simply supported and it can have rotations but no translations. The term simply supported indicates the constraints on the beam.
The loading scenarions on simple supported beams are multiples, such that: uniform load, load at center, load at any point of the beam, two equal loads(symmetrical placement of loads), uniform loads and overhanging symmetrical ends, uniform loads and overhanging unsymmetrical ends.
The following beam deflection fromulas are used in solving different problems,such that: slope at ends, deflection at any section(in terms of x), maximum and center deflection.
