I think torsional strain happens only when two groups are eclipsed in relation to their positions to each other. This strain can be relieved by rotation about the carbon carbon bond.
But steric strain can happen all the time. (when two groups are eclipsed, gauge or staggered in relation to each other.)
Steric strain refers to the repulsion between atoms in close proximity due to their electron clouds overlapping, leading to higher energy and destabilizing the molecule. Torsional strain, on the other hand, is caused by eclipsed interactions between substituents on adjacent atoms in a molecule, creating potential energy due to the unfavorable alignment of bonds. Both can contribute to the overall energy and stability of a molecular conformation.

What is strain energy due to torsion?
Strain energy due to torsion is the energy stored in a material when it is twisted under a torque load. It is calculated as the integral of shear stress and strain over the volume of the material. This energy represents the ability of the material to deform plastically under torsional loading.
What is the difference between normal strain and shear strain?
The normal strain is a deformation caused by normal forces such as Tension or Compression that act perpendicular to the cross-sectional area, while the shear strain is a deformation obtained from forces acting parallel or tangential to the cross-sectional area.
What is the Difference between strain gauge and extensometer?
A strain gauge is a sensor that measures strain or deformation in a material by changes in electrical resistance. An extensometer is a device that directly measures changes in length or extension of a material under load or stress. While both are used to measure deformation, strain gauges are more versatile and can be used in a wider range of applications compared to extensometers.
Difference between simple shear strain and pure shear strain of fabric?
Simple shear strain involves deformation by parallel sliding of fabric layers in opposite directions, resulting in stretching and compressing of the material. Pure shear strain occurs when fabric layers are displaced in opposite directions, causing the material to deform by shear without any change in volume. In simple shear, there is both shearing and stretching/compressing, while in pure shear, only shearing occurs.
What is the ratio between stress and strain called?
The ratio between stress and strain is called the modulus of elasticity or Young's modulus. It represents the stiffness or rigidity of a material and is a measure of how much a material deforms under stress.
What are the types of steric strain?
Van der Waals strain is one example
What is torsional force?
"Torsional strain" is the strain induced by applying torque. Basically, it is the strain imposed on a body by twisting it. (Such as the strain that a bolt endures when you use a wrench on it.)
When is Torsion used in everyday life?
When ever you cross a bridge torsional strain is at work, the engineers utilized it to determine the payload of each bridge and your car creates torsional strain on the bridges members.
What is a super coil?
It is what prevents DNA from torsional strain or winding up tightly.
Why are eclipsed confirmations more stable than staggered confirmations?
Eclipsed confirmations have higher torsional strain due to the steric hindrance from the eclipsing hydrogen atoms, making them less stable than staggered confirmations. In staggered confirmations, the groups are farther apart, reducing steric hindrance and leading to a more stable conformation.
What is the difference between repetitive stress injury and repetitive strain injury?
there is no difference

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.
Why is cis-2-butene less stable than trans-2-butene?
Cis-2-butene is less stable than trans-2-butene because of steric hindrance - in the cis form, the two bulky methyl groups are next to each other, causing repulsion and strain in the molecule. This strain is relieved in the trans form where the methyl groups are on opposite sides of the double bond, leading to a more stable conformation.
What is strain energy due to torsion?
Strain energy due to torsion is the energy stored in a material when it is twisted under a torque load. It is calculated as the integral of shear stress and strain over the volume of the material. This energy represents the ability of the material to deform plastically under torsional loading.
Why is the internal energy of cis isomers bigger than of trans isomers?
Cis isomers have higher internal energy compared to trans isomers due to the steric hindrance caused by the proximity of bulky substituents in the cis configuration. This leads to increased strain and repulsion between the atoms, resulting in higher internal energy. Trans isomers, on the other hand, have a more stable conformation with less steric hindrance.
What is difference between strain gauge and extensometer?
Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.
