3. A beam is a structural element that primarily resists  loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forcesand  bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape of cross-section), length, and their material. What is ?

4. Types of Beam Classification based on supports In engineering, beams are of several types There are manly Seven types of beam classified on the base of support 1. Double overhanging 5. Simply supported 2. Continuous 6 Fixed 3. Cantilever 7. Over hanging 4. Trussed

5. a beam supported on the ends which are free to rotate and have no moment resistance. Simply supported

6. a beam supported on both ends and restrained from rotation . Fixed

7. a simple beam extending beyond its support on one end. Over hanging

8. a simple beam with both ends extending beyond its supports on both ends. Double overhanging

9. a beam extending over more than two supports. Continuous

10. a projecting beam fixed only at one end. Cantilever

11. a beam strengthened by adding a cable or rod to form a truss Trussed
