Quick Answer: Which Material Is Least Elastic?

Why is rubber less elastic than steel?

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 is more elastic Mcq?

Air is more elastic than water.

Is rubber elastic or inelastic?

It is this constant jostling that produces a resisting (elastic) force in the chains as they are forced to become straight. While stretching a rubber sample is the most common example of elasticity, it also occurs when rubber is compressed.

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.

Why steel is most elastic?

So, it can be said that for a given amount of stress, the strain produced in the steel is comparatively smaller than the strain produced in the rubber. Therefore, with the help of Young’s modulus, it can be concluded that steel has greater elasticity than rubber.

Is wire elastic or inelastic?

Metal wires: inelastic, ductile.

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.

Is wood elastic?

Another unique property of wood is its viscoelasticity, which can be described as having both plastic and elastic characteristics when exposed to a certain deformation. Figure 1. Orthotropic structure of wood. Elastic materials easily stretch under an applied load.

Are Diamonds elastic?

Summary: Researchers have unveiled that brittle diamonds can be bent and stretched elastically when made into ultrafine needles. Diamonds is the strongest naturally occurring material on Earth. … “Ultrahigh elasticity of diamond is due to the paucity of internal defects.”

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.

Are all materials elastic?

To a greater or lesser extent, most solid materials exhibit elastic behaviour, but there is a limit to the magnitude of the force and the accompanying deformation within which elastic recovery is possible for any given 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.

Which is more elastic steel or glass?

Ductile materials are used for making springs and sheets. … Due to this reason, steel is preferred in making springs in comparison to steel. 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.

Which is more elastic quartz or steel?

Which is more elastic steel or quartz? … 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 .

Is aluminum more elastic than steel?

Steel is more elastic as Young modulus of elasticity less than Alumnium. So Aluminium exhibits more stiffness comparing to steel and it is brittle too. One can easily observe this property from aluminum foils used in house hold use seldom reusable as it can not return back to its orginal plain shape.

What are elastic materials?

1 Introduction. Elastomers are elastic materials that are characterized by large strain, high capability to recover the initial shape, nonlinear stress-strain curves and strain hardening [1–5]. … Elastomers can be compressed and due to their excellent elasticity retain the original shape.

Is Clay elastic or inelastic?

Examples: Rubber bands and elastic and other stretchy materials display elasticity. Modeling clay, on the other hand, is relatively inelastic and retains a new shape even after the force that caused it to change is no longer being exerted.

Which economics is more elastic?

Elasticity refers to the degree of responsiveness in supply or demand in relation to changes in price. If a curve is more elastic, then small changes in price will cause large changes in quantity consumed. If a curve is less elastic, then it will take large changes in price to effect a change in quantity consumed.

What happens when bodies are deformed beyond elastic limit?

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.

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 MetalsAluminum AlloysAluminum Alloy 356.072.410.5Copper AlloysMetalModulus of Elasticity53 more rows

What are the 4 types of elasticity?

Four types of elasticity are demand elasticity, income elasticity, cross elasticity, and price elasticity.
