unsymmetrical bending

Symmetrical bending occurs when a beam is loaded uniformly along its length, resulting in bending stresses that are equal on both sides of the beam's neutral axis. Unsymmetrical bending occurs when a beam is loaded unevenly, causing different magnitudes of bending stress on opposite sides of the beam's neutral axis.
Wave bending is called refraction. Refraction occurs when a wave changes direction as it passes from one medium to another at an angle. This change in direction is due to the difference in wave speed between the two mediums.
Shear force is the force perpendicular to the axis of an object, causing it to shear or slide. Bending moment is the measure of the bending effect of a force applied to an object, causing it to bend or deform. In essence, shear force is the force that tends to make a body slide or cut, while bending moment is the force that tends to make a body bend.
The light will bend away from the normal as it enters the material where its speed is higher. This bending of light is known as refraction. The amount of bending depends on the difference in the speed of light between the two materials.
Deviation refers to the bending of light as it passes through a medium or interface between two different mediums, causing the light to change direction. Refraction specifically refers to the bending of light as it passes from one medium to another, due to a change in the speed of light. So, deviation is a broader concept that includes refraction as a specific type.
The bending of light waves when they pass through another substance is called refraction. This phenomenon occurs because the speed of light changes when it travels from one medium to another, causing the light waves to change direction. The amount of bending depends on the difference in refractive index between the two substances.
