Modulus of elasticity is the measure of the stress–strain relationship on the object. Modulus of elasticity is the prime feature in the calculation of the deformation response of concrete when stress is applied. Elastic constants are those constants which determine the deformation produced by a given stress system acting on the material.

Shearing Stress is defined as: “ A type of stress that acts coplanar with cross section of material.”. Shear stress arises due to shear forces. They are the pair of forces acting on opposite sides of a body with the same magnitude and opposite direction. Shear stress is a vector quantity. Which means, here the direction is also involved.

The strain rate is a concept of materials science and continuum mechanics that plays an essential role in the physics of fluids and deformable solids. In an isotropic Newtonian fluid, in particular, the viscous stress is a linear function of the rate of strain, defined by two coefficients, one relating to the expansion rate (the bulk viscosity.

Entanglement is at the heart of quantum physics and future quantum technologies. Like other aspects of quantum science, the phenomenon of entanglement reveals itself at very tiny, subatomic scales. When two particles, such as a pair of photons or electrons, become entangled, they remain connected even when separated by vast distances.

Question 1. Diameter of a steel ball is measured using a vernier callipers which has divisions of 0.1cm on its main scale (MS) and 10 divisions of its vernier scale (VS) match 9 divisions on the main scale. Three such measurements for a ball are given as : If the zero error is – 0.03 cm, then mean corrected diameter is: (1) 0.53 cm (2) 0.56 cm

Announcing the winners, the Nobel Prize committee said: “The 2022 physics laureates’ development of experimental tools has laid the foundation for a new era of quantum technology. “Being able to manipulate and manage quantum states and all their layers of properties gives us access to tools with unexpected potential.”

Quantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to. The descriptor \quantum" arises because in contrast with classical mechanics, certain quantities take on only discrete values.
