Stress refers to external forces applied to a material, while strain refers to the deformation or change in shape of the material resulting from those stresses. Hooke's law states that within the elastic limit, the amount of strain produced is directly proportional to the stress applied. Different moduli describe the relationship between stress and strain, including Young's modulus, the bulk modulus, and the shear modulus. Stress and strain can be longitudinal, relating to changes in length, or transverse, relating to changes in width or thickness. The elastic limit is the maximum stress a material can withstand without permanent deformation, after which plastic deformation or fracture may occur.

Properties of matter Class XI

- Elasticity is the property of an object to regain its original shape after a deforming force is removed. The limit of deforming force where an object fully regains its shape is called the elastic limit.
- Stress is defined as the internal restoring force acting per unit area of a deformed object. Stress can be normal or tangential depending on the direction of the deforming force.
- Strain is defined as the fractional change in configuration of an object. The ratio of stress to strain within the elastic limit is a material property called modulus of elasticity or Young's modulus.

Hooke’s law

Hooke's law states that the deformation of an elastic object is proportional to the applied force. For relatively small deformations, the amount of displacement is directly proportional to the deforming force. The concept is that the amount of force applied to a spring or elastic object is proportional to the amount of deformation. The greater the force applied, the more the object deforms through stretching or compression. Hooke's law is represented by the formula F=kx, where F is the applied force, k is the force constant, and x is the deformation.

Hook's law

Hooke's Law describes the relationship between the force applied to an unstretched spring and the amount it is stretched. An experiment is conducted to determine how the extension of a spring varies with the stretching force. Weights are added to a spring in stages and the extension is measured. The results show that the extension is directly proportional to the applied force, as predicted by Hooke's Law, but only up to a certain point known as the elastic limit. Beyond this point, the spring undergoes plastic deformation and does not return to its original length when the force is removed.

Stress,strain,load

Loads can be tensile (pulling) or compressive (pushing) forces. Common types of loads include dead loads from structural weight, live loads from moving objects, impact loads from vibrations, and cyclic loads from repeated forces. When loads are applied, they cause stress in materials. Stress is the internal resisting force per unit area. Stresses can be tensile (pulling), compressive (pushing), or shear (tangential). Corresponding strains are the changes in dimensions from stresses. Hooke's law states that within the elastic limit, stress is proportional to strain by a constant modulus of elasticity.

1-Machine design - Stresses in Machine Members (2) - Copy.pptx

Types of stresses include tensile, compressive, shear, torsional, and bearing. Stresses are caused by external forces and loads acting on a body. Stress is equal to force divided by cross-sectional area. Strain is the deformation or change in length caused by stresses. Hooke's law states stress is proportional to strain. Shear stress is caused by tangential forces across a section and shear strain is the resulting angular deformation. Torsional shear stress results from opposing torque or twisting moments.

Diploma sem 2 applied science physics-unit 2-chap-1 elasticity

Elastic and plastic deformation are described. Elastic deformation is reversible and no permanent change occurs. Plastic deformation results in a permanent change in shape as interatomic bonds are broken. Stress is defined as force over area, and strain as the ratio of deformation to original length. Hooke's law states that stress is proportional to strain within the elastic limit. The elastic moduli - Young's modulus, shear modulus, and bulk modulus - are defined relating stress and strain. Poisson's ratio describes the lateral contraction that occurs during stretching. Examples show calculations of stress, strain, and dimensions based on given loads and properties.

The decibel is a logarithmic unit used to express the ratio of two power levels or amplitudes. It is commonly used to measure sound levels or power in electronic systems. A decibel represents one tenth of a bel, with 0 dB representing a ratio of 1. Power gain in decibels is calculated as 10 times the log of the ratio between output and input power. A doubling of power equals a 3 dB gain. Total system gain is the sum of individual stage gains. Attenuation is expressed as a negative decibel value. Voltage and current gains can also be expressed in decibels by taking the log of the ratio of output to input levels.

Anti-Universe And Emergent Gravity and the Dark Universe

Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...

Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.
