Quartz has more elasticity as compared to steel.
Which is more elastic steel or glass?
The Coefficient of elasticity of glass is between 50 and 90; the Coefficient of elasticity of steel is 210; the Coefficient of elasticity of Copper is 120. Therefore, the rubber is more elastic than glass and glass is more elastic than copper and copper is more elastic than steel.
Which is the most elastic?
Elasticity 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.
Why quartz is perfectly elastic?
There is no perfectly elastic body but quartz fibre and Phosphor bronze are examples of near perfect elastic bodies. ... Because of elasticity, the ball tends to regain its original shape for which it presses the ground and bounces up .
Is rubber elastic or plastic?
Rubber can be considered elastomers, and that’s why when compared to plastics, they are naturally more elastic . 2. Synthetic rubber is derived from crude oil, whereas synthetic plastic is made of petroleum and natural gas.
Why steal is more elastic than rubber?
The ratio of stress applied on a body to the strain produced in it is defined as the Young’s modulus of that material. ... The strain produced in rubber is much larger compared to that in steel. This means that steel has a larger value of Young’s modulus of elasticity and hence, steel has more elasticity than rubber.
Why steal is more elastic than copper?
Answer: 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. ...
Which material is least elastic?
Rubber is the least elastic material.
Is Cotton most elastic?
Cotton elastic is very soft and absorbent . ... Cotton is a much more expensive fiber than synthetics such as nylon elastic, polyester elastic or polypropylene elastic.
Which metal is most elastic?
Which is more elastic glass or steel ? Steel is more elastic than rubber. This is explained with the help of Young’s modulus.
Is air more elastic than water?
Water is more elastic than the air because we know that the bulk modulus of elasticity is reciprocal of compressibility. So the answer is water is more elastic than air because it is less compressible than the air.
Does quartz show elastic effect?
Quartz shows six independent elastic constants , and our estimates of these constants are close to those computed by other means. Except for C14, after a 1% mass-density correction, natural quartz and cultured quartz show the same elastic constants. Natural quartz shows higher internal frictions.
Which material is perfectly elastic?
Answer: All materials undergo a change in their original state, howsoever small it may be, after the removal of deforming force. Hence, there is no such material which is perfectly elastic .
What happens to elastic body when elastic limit is crossed?
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. ... For most brittle materials, stresses beyond the elastic limit result in fracture with almost no plastic deformation.
Does rubber contain plastic?
Plastics are derived from materials found in nature, such as natural gas, oil, coal, minerals and plants. The very first plastics were made by nature—did you know that rubber from a rubber tree is actually a plastic ? ... The first synthetic plastics were derived from cellulose, a substance found in plants and trees.
