How does the elasticity of material change?
Temperature: As the temperature increases, intermolecular forces decreases, resulting in a decrease in the elasticity.
Impurities: Depending on the nature of the impurities, the elasticity of a material can either increase or decrease..
What is elasticity of demand definition?
Answer: By definition, The elasticity of demand is the change in demand due to the change in one or more of the variable factors that it depends on. … The responsiveness of the quantity demanded to the change in income is called Income elasticity of demand while that to the price is called Price elasticity of demand.
What modulus of elasticity tells us?
Modulus of Elasticity, also known as Elastic Modulus or simply Modulus, is the measurement of a material’s elasticity. Elastic modulus quantifies a material’s resistance to non-permanent, or elastic, deformation. … Modulus is defined as being the slope of the straight-line portion of a stress (σ) strain (ε) curve.
What are the applications of elastic Behaviour of materials?
Application of Elastic Behavior of Materials The theory of elasticity is used to design safe and stable man-made structures such as skyscrapers and overbridges to make life convenient. Cranes used to lift loads use ropes that are designed so that the stress due to the maximum load does not exceed the breaking stress.
Which is elastic material answer?
Answer. Practically everything around us in elastic to certain extent. The most elastic body found so far in modern science is quartz fibre. Apart from that elastomers are the class of polymer materials with high elastic nature and they include natural rubbers,nitrile rubbers etc.
How do you determine the elasticity of a material?
One important way to measure elasticity is to calculate the elastic modulus (also known as Young’s modulus) of the material. The elastic modulus (E) is defined as the stress applied to the material divided by the strain.
What are examples of elastic materials?
The materials that can be stretched and when released attains their original shape and size are known as elastic materials. Rubber band is an example of elastic material.
What is the least elastic material?
RubberRubber is the least elastic material.
Which is more elastic steel or copper?
Elasticity of steel is more than that of copper and so for equal applied force, the elongation of steel spring is less than that of copper for same initial length. … Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than produced in rubber.
Is elastic modulus the same as Young’s modulus?
Young’s modulus, also referred to as elastic modulus, tensile modulus, or modulus of elasticity in tension is the ratio of stress-to-strain and is equal to the slope of a stress–strain diagram for the material.
What is elastic limit?
Elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape. Stresses beyond the elastic limit cause a material to yield or flow.
What are the factors which affect the elasticity of a material?
Apart from elastic fatigue some material will have change in their elastic property because of the following factors.Effect of stress.Effect of annealing.Change in temperature.Presence of impurities.Due to the nature of crystals.Dec 9, 2016
What are the elastic properties of materials?
In many materials, when the stress is small, the stress and strains are linearly proportional to one another. The material is then said to obey Hooke’s Law. The ratio of stress to strain is called the elastic modulus. Hooke’s Law only holds for a range of stresses, a range referred to as the elastic region.
What material is most elastic?
rubberElasticity is the ability of a material to regain its own original shape after being stretched according to which, rubber is the most elastic substance.
Which is more elastic Mcq?
Air is more elastic than water.
What is effect of annealing on elasticity of materials?
Annealing is a process by which we heat a given object to make it more workable by increasing its ductility and decreasing its hardness as a result its elasticity decreases. while for hammering the crystal grains break up into smaller units owing to which the elastic property of the material increases.
What are the 3 modulus of elasticity?
There are three modulus of elasticity namely Young’s modulus (Y), Bulk modulus (K) and modulus of rigidity (η) corresponding to three types of the strain.
What is elastic material?
Elastic materials extend when being stretched and quickly return to their original state once the load is removed.
