What is the simple definition of strain?
strain, in physical sciences and engineering, number that describes relative deformation or change in shape and size of elastic, plastic, and fluid materials under applied forces. Strains may be divided into normal strains and shear strains on the basis of the forces that cause the deformation.
What is breaking strength in physics?
Here, breaking strength refers to the amount of force which can be applied to a string before it breaks.
What does breaking load mean?
Load which causes fracture in a tensile, compression, flexure or torsion test. In tensile tests of textiles and yarns, breaking load also is called breaking strength.
What is breaking stress class 11?
Breaking stress is the maximum stress that the body can withstand before it finally breaks. It is defined as the ratio of braking force per unit area. Breaking stress is also known as the ultimate tensile stress or breaking strength.
What is meant by strain in physics?
Strain is simply the measure of how much an object is stretched or deformed. Strain occurs when force is applied to an object. Strain deals mostly with the change in length of the object.
What does strain mean in biology?
Strain. A tearing injury to muscle. Usually causes some degree of bleeding within the muscle tissue (haematoma). (biology) a group of organisms within a species that differ in trivial ways from similar groups; a new strain of microorganisms.
What is tensile strain answer?
Tensile strain is defined as the deformation or elongation of a solid body due to the application of a tensile force or stress. In other words, tensile strain is produced when a body increases in length as applied forces try to “stretch” it. Tensile strain can be expressed mathematically by the formula: ε = ΔL / L.
What is breaking strength of a string?
In a simple pendulum, the breaking strength of the string is double the weight of the bob. The bob is released from rest when the string is horizontal.
What is Max breaking load?
WLL refers to the maximum allowed weight that a particular piece of rigging can handle under normal conditions. WLL is 1/3 of the breaking strength rating, therefore a strap with a WLL of 6,000 pounds would have a breaking strength of 18,000 pounds.
What is the breaking point of steel?
The breaking strength for structural steel is 400 megapascals (MPa) and for carbon steel is 841MPa.
What is strain Wikipedia?
Strain (chemistry), a chemical stress of a molecule. Strain (injury), an injury to a muscle (tear in tendon) in which the muscle fibers tear as a result of over-stretching. Strain (mechanics), a geometrical measure of deformation representing the relative displacement between particles in a material body.
What is meant by lateral strain?
From Wikipedia, the free encyclopedia. In continuum mechanics, lateral strain, also known as transverse strain, is defined as the ratio of the change in diameter of a circular bar of a material to its diameter due to deformation in the longitudinal direction.
Which is the breaking point in the stress strain curve?
(v) Fracture or Breaking Point. It is the point in the stress-strain curve at which the failure of the material takes place. Hooke’s Law. In the 19th-century, while studying springs and elasticity, English scientist Robert Hooke noticed that many materials exhibited a similar property when the stress-strain relationship was studied.
Which is the correct definition of the term strain?
What is Strain? According to the strain definition, it is defined as the amount of deformation experienced by the body in the direction of force applied, divided by initial dimensions of the body. The relation for deformation in terms of length of a solid is given below. L is the original length of the material.
Who is the author of the book Breaking Strain?
For the concept, see Deformation (physics). ” Breaking Strain “, also known as ” Thirty Seconds Thirty Days “, is a science fiction short story by English writer Arthur C. Clarke, first published in 1949. It was adapted into a movie in 1994 under the title Trapped in Space.
What happens when a strain is applied to a material?
Materials cannot stretch forever. When a strain is applied to a material it deforms elastically proportional to the force applied. However, after it has deformed a certain amount, the object can no longer take the strain and will break or fracture. The zone in which it bends under strain is called the elastic region.
