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..
Which one has maximum elastic limit?
rubberIt is the highest limit of the material before the plastic deformation of the material can occur. Once the stress or force is removed from the material, the material comes back to its original shape. Elastomers like rubber have the highest elastic limit.
Which is more elastic iron or rubber and why?
Iron is more elastic than rubber because The elastic modulus of the more substance is more elastic.
Which is more elastic plastic or steel?
Answer. By definition steel is more elastic than plastic because it regain its original shape faster than rubber after removal of deforming force.
Why is rubber so elastic?
When molecules form crystals they give off heat hence the reason the rubber band gets hot when stretched. When you let go of the rubber band the polymer molecules break out of the crystals.
Is rubber elastic or plastic?
1. 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 glass is more elastic than rubber?
(a) Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than the strain produced in rubber.
Why is spring made of steel not copper?
Solution : A spring will be better one, if a large restoring force is setup in it on being deformed, which in turm depends upon the elasticity of the material of the spring. Since the Young’s modulus of elastivity of steel is more than that of copper. Hence steel is prefferred in making the spring.
Which material is least elastic?
RubberRubber is the least elastic material.
Is Brass more elastic than steel?
Solution : Steel is more elastic than copper, brass and aluminium . Because of this reason steel is preferred in heavy duty, machines and in structural designs.
Which is more elastic iron or steel?
Elasticity is an objects ability to return to its original size and shape when a force is applied then subsequently removed. In general, iron is more elastic. Steel has more stiffness.
Which 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. But when we define elasticity in physics it is the ratio of stress to strain. It means that the shape which has more resistance to change is more elastic.
Which is more elastic diamond or steel?
Steel is more elastic than diamond . Steel have youngs modulus value of 200gpa. Diamond have youngs modulus value of 1200gpa. … Between diamond and steel , steel have more elastic nature.
Which is more elastic rubber or steel prove mathematically?
Answer. Elasticity is measured on a stress-strain diagram. … that means the same stress causes plastic deformations in the rubber sample while the steel sample returns to the no-stress configuration. That’s how steel can be more elastic than rubber.
Which is more elastic Mcq?
Air is more elastic than water.
