A beam is a structural element that primarily resists loads applied laterally across the beam's axis (an element designed to carry a load pushing parallel to its axis would be a strut or column).
A beam is a structure, which is loaded transversely (sideways). The loads may be point loads or uniformly distributed loads (udl). The diagrams show the way that point loads and uniform loads are illustrated.

In civil engineering, there are four main types of beams: simply supported beams, fixed beams, cantilever beams, and continuous beams. However, there are numerous subtypes based on shape, equilibrium conditions and load-bearing characteristics.
For other uses, see Bending (disambiguation). In applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element.

Beams of Light can be of 3 types. They are parallel, convergent and divergent. Parallel:When Rays from a distant point source travel parallel to each other in a particular direction, it forms a parallel Light Beam. The sunRay is an example of a parallel Beam of Light. Convergent:In a convergent Beam, the Light Rays from a source of Light, eventuall...
Light Rays change their direction while moving from one medium or when they are reflected off a surface. The law of Reflection states that a Light Ray reflecting off an even surface has an equal angle of incidence and angle of Reflection.
When a Light Ray travels from one transparent medium to another transparent medium, a portion of the Light is reflected and another portion of the Light is transmitted into the second transparent medium, changing the direction of the Light. This phenomenon is defined as the Refraction of Light. The law of Refraction or Snell's law states that the r...
ratio of sin θ1and sin θ2(sin θ1/ sin θ2) = ratio of refractive index (n1/ n2) or, n1sin θ1= n2sin θ2 Where, θ1= angle of incidence θ2= angle of Refraction The index of Refraction of medium 1 and 2 are n1and n2, respectively A Light Ray from a Lighter medium when entered into a denser medium bends towards the normal of the surface. On the other han...
The ratio of the speed of Light in a vacuum to its speed in that particular medium is known as the refractive index or index of Refraction. For example, the refractive index for a vacuum is always 1. The refractive index of air (standard conditions) is 1.0003, water is 1.3, and that of glass is 1.5. By the law of Reflection and the law of Refractio...
There are three different types of Light Beams, namely Parallel. Convergent and Divergent A Beam of Light Rays that are given out from a source is known as a Beam of Light. While moving from one medium, or when Light is reflected off a surface, Light Rays change their direction. On Reflection from a smooth surface, the angle of the Ray that is refl...
Jul 15, 2014 · A beam is defined as an element that is structural in nature and one that can resist load primarily by bending. Historically speaking, beams were the squared timbers, however, over the time we have witnessed beams made of a number of materials.
Sep 18, 2003 · This chapter explores the physics of photons, both as beams in their own right, and as the phenomena of photon emission and absorption affect charged particle beams. It begins by introducing the photon, a categorisation of its wave and particle-like properties, and a comparison of these properties with those of charged particles.
