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. The larger strain means the material is less elastic.
Which is more elastic between rubber and steel?
If the same amount of force is applied to a steel wire and to a wire made of rubber of same length and cross-sectional area, the extension of rubber wire is easier than the extension of the steel wire. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.
Which is stronger steel or rubber?
Adding this material could make rubber bands nearly unbreakable, without losing elasticity.
Why is glass elastic?
Whilst the resistance of glass to compression stress is extremely high, its resistance to tensile stress is significantly lower. Glass is a perfectly elastic material: it does not exhibit permanent deformation, until breakage. However it is fragile, and will break without warning if subjected to excessive stress.
Which is more elastic Mcq?
Air is more elastic than water.
Which is more elastic quartz or steel?
The elastic modulus of quartz is 98 Gp and the elastic modulus of steel is around 200 GP (approx.) . So , according to this steel can take more amount of stress . So , steel is more elastic and can return to original shape .
Which is more elastic Aluminium or copper?
If the Young modulus of metal is greater, it’s stiffer. Modulus of elasticity is an important design factor for metals for calculations of elastic deflections.MODULUS OF ELASTICITY FOR METALS.
| Modulus of Elasticity Values for Metals | ||
|---|---|---|
| Aluminum Alloys | ||
| Metal | Modulus of Elasticity | |
| GPa | 106 psi | |
| Copper Alloy C11000 (electrolytic tough pitch) | 115 | 16.7 |
Is Iron more elastic than rubber?
Since, the iron rod regains its original configuration more efficiently than rubber, it is iron which is more elastic than rubber. However, the iron rod is less plastic because it shows more tendency to return to its original configuration after the deforming forces are removed.
What objects are elastic?
Many objects are designed specifically to store elastic potential energy, for example:
- The coil spring of a wind-up clock.
- An archer’s stretched bow.
- A bent diving board, just before a divers jump.
- The twisted rubber band which powers a toy airplane.
- A bouncy ball, compressed at the moment it bounces off a brick wall.
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.
Is glass more elastic than steel?
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.
What are the 4 types of elasticity?
Four types of elasticity are demand elasticity, income elasticity, cross elasticity, and price elasticity.
Is rubber elastic or plastic?
Rubber is an example of elastic materials. Any metallic materials will be an example for plastic materials.
Which material is least elastic?
Rubber is the least elastic material.
Which one has maximum elastic limit?
It 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.
Why steel is more elastic than rubber Quora?
Steel is more elastic than rubber because when the deforming forces ( the forces which cause the body to deform ) are removed from steel, it comes back fast to its original shape faster than rubber. And since strain is smaller for steel than rubber, it is more elastic than rubber.
Which has more Youngs modulus steel or rubber?
The modulus of elasticity of steel is greater than that of rubber because under the same stress. Modulus of elasticity is inversely proportional to strain for a given stress. If steel and rubber are under the same stress, the strain in steel is less than rubber . Hence steel is more elastic than rubber.
Why is rubber so elastic?
Natural rubber is made of long chains of molecules called polymers. Because these polymers are so long (they can be thousands of molecules long) they get tangled up in themselves. The result is a property called elasticity, the polymers are elastic. This is why rubber bands are sometimes called elastic bands.
What is elastic limit?
A material’s elastic limit is the greatest stress that can be applied to it without causing plastic (permanent) deformation. When a material is stressed to a point below its elastic limit, it will return to its original length once the stress is removed.
Is rubber a ductile material?
RUBBER IS DUCTILE DUE TO ITS SPECIAL PROPERTY OF ELASTICITY. BUT AFTER REACHING THE FRACTURE POINT THE ELASTIC LIMIT OF RUBBER ENDS.
Which is more elastic steel or 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. Oct 25, 2019
What elasticity means?
Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically.
Why steal is more elastic than rubber?
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. Rubber gets stretched because there is strain produced in it when stress is applied.
Which material 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 water or air or solid or Crystal?
Answer. Water is more elastic than air because bulk modulus of elasticity is reciprocal of compressibility and air is more compressible than water.
