What is the unit of strain energy?
The unit of strain energy is the joule (J), which is equivalent to a force of one newton applied over a distance of one meter. Strain energy represents the energy stored within a material due to deformation caused by applied forces or stresses.
Which type of strain is there when a spiral spring is stretched by a force?
When a spiral spring is stretched by a force, it experiences tensile strain. Tensile strain occurs when an object is stretched or pulled in opposite directions, causing the material to elongate. This type of strain is defined as the change in length per unit original length of the material.
What is the formula of modulus of elasticity?
The modulus of elasticity (also known as Young's modulus) is calculated using the formula E = stress/strain, where E is the modulus of elasticity, stress is the force applied per unit area, and strain is the resulting deformation or elongation.
Why stres is directly proportional to strain?
Yeah, according to the Hooke's law of elasticity,the stress is proportional to the strain within elastic limit that is Stress ∝ Strain or Stress/Strain = constant. [The constant of proportionality is called as "modulus of elasticity" or "coefficient of elasticity".]
Which of the following is dimensionless quantity a. stress b. strain c. momentum d. force?
Strain is dimensionless quantity because strain is the ratio of the same quantities like change in length/original length,,change in volume/original volume. e.g tensile strain=(change in length)/(original length)=m/m (S.I unit) so its a dimensionless quantity.
What is the unit of strain?
strain has no unit
Could you show the derivation of elastic strain energy per unit volume?
The elastic strain energy per unit volume, also known as the strain energy density, can be derived by integrating the stress-strain curve over the strain range. The area under the stress-strain curve represents the work done on the material, which is equivalent to the strain energy stored. By dividing this strain energy by the volume of the material, the strain energy density per unit volume can be obtained.
What is stress Strain?
Stress is the amount of force per unit area (N/mm2; lb/ft2) Strain is the unitless change in length resulting from the application of a force (movement in unit length / original unit length) Young's Modulus relates the two (stress / strain)
Why does a strain doesn't have a unit?
Because it is the ratio of two lengths.
What is the difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What is the unit of strain energy?
The unit of strain energy is the joule (J), which is equivalent to a force of one newton applied over a distance of one meter. Strain energy represents the energy stored within a material due to deformation caused by applied forces or stresses.
What is strain in physics?
Strain is the change in dimensions per unit original dimensions. For example, if your stretch a 100 cm long wire by 5 cm, Strain = 5/100 = 0.05
What are the ratings and certificates for Law and Order Special Victims Unit - 1999 Strain 7-5?
Law and Order Special Victims Unit - 1999 Strain 7-5 is rated/received certificates of: USA:TV-14
Why strain has no unit?
Strain is a dimensionless quantity that represents the deformation of an object relative to its original size. It is calculated as the change in length divided by the original length, making it unitless. This is because strain is a ratio of two lengths, and as such, it does not require a unit to quantify its value.
What is the work of strainer in fan coil unit?
To strain waste particles in chilled water
Which one of the following physial quantities does not have the dimensions of force par unit area A stress A strain C young' modulus D pressure?
option b strain
What is strain and stress?
stress is load per unit area; when an object is loaded it is under stress and strain and it stretches (strains) until it breaks at its ultimate strength. Stress i srelated to strain in the elastic region by Hooke's law: stress = elastic modulus times strain where modulus is a property of the material and strain is deflection over length
