Can A Force Deform A Given Body?

What are the 2 types of deformation?

Deformation can be of two types as follows:Permanent Deformation – Also known as plastic deformation, it is irreversible.

It is a type of deformation that stays even after the removal of applied forces.Temporary Deformation – Also known as elastic deformation, it is reversible..

What is permanent deformation?

Permanent deformation and factors affecting it. Strain is defined as a change in length expressed as a function of the length being changed i.e. … Deformation in an ideally elastic material is totally recoverable. Once the stress is no longer applied, the object returns to its original shape.

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.

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.

What are the 3 types of deformation?

When a rock is subjected to increasing stress it passes through 3 successive stages of deformation. Elastic Deformation — wherein the strain is reversible. Ductile Deformation — wherein the strain is irreversible. Fracture – irreversible strain wherein the material breaks.

Which is the 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.

What are the 5 effects of force?

A force can produce the following effects: A force can move a stationary object. A force can stop a moving object. A force can change the speed of a moving object. A force can change the direction of a moving object. A force can change the shape and size of an object.Mar 20, 2019

What is a plasticity?

Plasticity, ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behaviour, and those causing failure of the material, or rupture (see yield point).

What are deforming forces?

If this results in change in the configuration of length, volume or shape of the body then the force applied is called as deforming force. … The force which restores the size and shape of the body when deformation forces are removed is called restoring force .

When force is applied on a body size and shape of body changes and the body is said to be?

If a force on a body changes the normal positions of the molecules of a body, resulting in a change in the configuration of the body, then the force applied is called deforming force and change in shape of the body is called deformation.

Which force arises when a body deforms?

deforming forcesThe forces which produce deformation in the body are called deforming forces.

What is deforming force in elasticity?

The external force acting on a body on account of which its size or shape or both change is defined as the deforming force. Restoring force : The force which restores the size and shape of the body when deformation forces are\ removed is called restoring force.

What is elastic limit in physics?

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.

Which force is responsible for the elastic nature of a body?

Restoring forceRestoring force is responsible for the elastic behavior of substance because it is this force which tends of restore the original configuration of the body, whereas the deforming force applied on the body produces only the extension or compression in it.

Why steel is more elastic than rubber?

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.

What is the rock deformation?

Within the Earth rocks are continually being subjected to forces that tend to bend them, twist them, or fracture them. When rocks bend, twist or fracture we say that they deform (change shape or size). The forces that cause deformation of rock are referred to as stresses (Force/unit area).

When a force is applied on a body what are the two effects it can produce?

Force and Pressure | Short/Long Answer Questions Solution: Two effects of a force applied on a body are: (i) It can change the state of movement of the body on which force is applied, i.e. it can move a stationary object or stop a moving object. (ii) It can change the shape and size of an object.

What is the other name of moment of force?

For example, the moment of force, often called torque, is the product of a force on an object and the distance from the reference point to the object.
