How do you calculate elastic force?

In order to find the formula for elastic potential energy of a spring we need to look at Hooke’s law, which states that the force needed to stretch a spring is proportional to the displacement of the spring. Mathematically this is expressed as F = kx, where x is the displacement and k is the spring constant.

What is the elastic force?

Elastic Force The force that allows some materials to return to its original shape after being stretched or compressed.

What is the formula for elastic force Mcq?

The law states that the strain in a solid is proportional to the applied stress within the elastic limit of that solid body i.e. stress = k x strain.

What is elastic force example?

1.An example of elastic force is bungee jumping.

The farther the elastic is stretched, the more force it exerts to return back to its original shape. The jumper is being pulled down to the ground by gravity, and the cord, resisting and trying to pull back to its original shape and length, is exerting the elastic force.

Which is more elastic Mcq?

Explanation: Air can be compressed easily while water is incompressible and bulk modulus is reciprocal of compressibility. Therefore, water is more elastic than air.

What is volume modulus of elasticity?

The Bulk Modulus Elasticity can be calculated as. K = – dp / (dV / V₀)

What is the unit of elastic modulus Mcq?

What is the unit of elastic modulus? Explanation: Elastic modulus is expressed in GPa. Mohs is the unit used for hardness. Stress is measured in MPa.

What are the three formulas of force?

The three major equations that will be useful are the equation for net force (F_net = m•a), the equation for gravitational force (F_grav = m•g), and the equation for frictional force (F_frict = μ•F_norm).

What is a stretching force?

Tensional force is a force applied by an object being stretched. The object being stretched might be a rope, a string, an elastic band or a wire. The tensional force of the object is applied on the objects that are stretching it. Tensional force is directed along the stretched object.

What is gravitational force Class 5?

Solution : Gravitational force is the force of attraction on a body by earth. Example – Leaves and fruits fall from a tree downwards towards the ground due to the gravitational pull.

What do you mean by viscous force?

A measure of a fluid’s resistance to flow. Viscous forces in a fluid are proportional to the rate at which the fluid velocity is changing in space, the proportionality constant is the viscosity.

What is spring force?

Spring force is the force required or exerted to compress or stretch a spring upon any object that is attached to it. When an object applies a force to a spring, then the spring applies an equal and opposite force to the object. It always acts so as to restore mass back toward its equilibrium position.

What is elasticity in stretching?

Tissue elasticity is the ability to stretch a muscle to reach its full range of movement without restriction.

What is the equation for potential energy of a spring?

Potential Energy of a Spring Formula

String potential energy = force × distance of displacement. Also, the force is equal to the spring constant × displacement. P.E.

Is elastic and spring force the same?

Yes, both are the same. It’s due to the property of materials – called elasticity. When we try to deform the body, internal restoring forces will develop and these forces e equal and opposite to the applied force. This is called spring force or the restoring force.

Are all metals elastic?

Corrosionpedia Explains Elasticity of Metal

The elastic deformation of a metal is a reversible occurrence where the metal can return to its original state. Metals that are deformed past the point where a return to their original state is impossible are referred to as being plastically deformed and not elastic.

How elastic force is used to shoot an arrow from a bow?

The archer holds the feather end of the arrow against the string while pulling it back. Releasing the string thrusts the arrow forward with the elastic force of the bow. The elastic potential energy of the bow is converted to the kinetic energy of the arrow.

Are Diamonds elastic?

Diamond is the hardest natural material, but its practical strength is low and its elastic deformability extremely limited.

What is the dimensional formula of modulus of elasticity?

So, modules of elasticity = [ML−1T−2]

Which law is also called as the elasticity law?

EXPLANATION: Hooke’s law is valid only under the elastic limit of a body i.e. stress is proportional to the strain within the elastic limit. Hence, it also referred to as the elasticity law.

What is strain formula?

The strain formula is: S = frac{Delta x}{X} Here, S = strain (it is unitless) Delta x = change in dimension. X = original dimension.

How do you find Poisson’s ratio?

Finally, Poisson’s ratio can be calculated. Poisson’s ratio = ν = − ε y ε x = Radial strain Axial strain = 0.0023 0.015 = 0.16 .

What is elastic modulus in physics?

Elastic modulus is a quantitative measure of how much something wants to return to its original shape and size. Generally it can be thought of as stress over strain. We calculate the elastic modulus by using the formula applied pressure / fractional change in size.

How is Young’s modulus of elasticity defined Mcq formula?

Young’s modulus: Young’s modulus a modulus of elasticity, applicable to the stretching of wire, etc., equal to the ratio of the applied load per unit area of the cross-section to the increase in length per unit length. It is denoted as E or Y. The unit of Young’s modulus is N m-2.

What is a factor controls the elastic modulus?

The porosity of aggregate significantly influences the elastic modulus, aggregate with low porosity results in high modulus of elasticity.

What is the ratio of Young’s modulus?

Young’s modulus, also referred to as elastic modulus, tensile modulus, or modulus of elasticity in tension is the ratio of stress-to-strain and is equal to the slope of a stress–strain diagram for the material.

What is the formula of 1 Newton?

At average gravity on Earth (conventionally, g = 9.80665 m/s²), a kilogram mass exerts a force of about 9.8 newtons. An average-sized apple exerts about one newton of force, which we measure as the apple’s weight. 1 N = 0.10197 kg × 9.80665 m/s² (0.10197 kg = 101.97 g).

Where is elastic spring force?

Elastic spring force is the force acting on a stretched/compressed elastic object to return it to its original length. Firstly, let us recall the 2 factors that affect elastic spring force: Factor 1: The extent to which (how much) the elastic object is stretched or compressed.

How does elastic spring force work?

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object.

What is gravitational force class 7th?

The universal law of gravitation states that every object in the universe attracts every other object with a force called the gravitational force. The force acting between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
