Strain is the change in dimensions per unit original dimensions. For example, if your stretch a 100 cm long wire by 5 cm, Strain = 5/100 = 0.05

Examples of longitudinal strain in physics include the stretching or compression of a spring when a force is applied, the elongation of a rubber band when pulled, and the contraction of a metal rod when cooled. These examples demonstrate how materials deform along their length in response to applied forces.
In physics, stress is the force applied to an object, while strain is the resulting deformation or change in shape. The relationship between stress and strain is described by the material's stiffness, known as Young's modulus. This relationship helps scientists understand how materials respond to external forces and can be used to predict their behavior under different conditions.
hook'law state that when a force is applied to the body then the stress produced in the body is directly propotional to the strain within the elastic limit stress = e & strain
In physics, stress is the force applied to a material, while strain is the resulting deformation or change in shape. The relationship between stress and strain in materials is explained by the concept of elasticity, which describes how materials respond to stress by deforming and returning to their original shape when the stress is removed. This relationship is typically represented by a stress-strain curve, which shows how a material deforms under different levels of stress.
In physics, strain refers to the deformation or displacement of a material due to applied stress. It is a measure of how much a material deforms under loading compared to its original shape. Strain can be expressed as a ratio or percentage of the change in size or shape of an object.
Use the formula Strain=Extension/original length and rearrange to give Original length=Extension/Strain. Substitute the values you have for the strain and the extended length into the equation and voila! Source: Doing A-level (senior high-school in America) Maths and Physics.
The S strain produces a capsule but the R strain does not
In terms of me physically studying it, never again as I suffered terribly in my lessons. In terms of in life, through secondary school, then college, then Uni, then further on in an institute of physicists. In terms of requirement, If you study engineering, for example, you will most likely study physics for forces, stress and strain, aerodynamics etc...
The three types of strain are tensile strain, compressive strain, and shear strain. Tensile strain occurs when an object is stretched, compressive strain occurs when an object is compressed, and shear strain occurs when two parts of an object slide past each other in opposite directions.
