The beam is not necessarily a support, it can itself be a structure for example bridges and balconies. What is a beam?Ī beam is a structural element that is mainly used for supporting the primary structure. In further sections we shall see the mathematical forms of bending stress for various beam configurations and cross sectional shapes. It is simply the stress which is responsible for bending of the work piece. Let us start our discussion with the definition of bending stress. The bending strength of the material is the maximum amount of bending strength that can be applied on the work piece before the work piece starts to fracture. The work piece will break if the applied bending stress exceeds more than the maximum allowable bending stress. It is very important to know the amount of bending stress being experienced by the work piece. We all know that when an object curves due to application of load then it is said to be subjected under bending. This article discusses about bending stress formula for different types of beam configurations.
