Stringing chart
•
0 likes•86 views
Stringing chart is a graph that shows the relationship between sag, tension, and temperature for overhead power lines. It is used because sag increases with lower tension, while lower tension results in higher sag. The stringing chart helps compromise between low sag and low tension by accounting for the effect of temperature on this relationship.

Magnetic moment & variation with temperature by Dr. Narinderjit
This document discusses the relationship between magnetic susceptibility and temperature. It presents Curie's Law which states that magnetic susceptibility is inversely proportional to temperature. It also introduces the Curie-Weiss Law which includes the Weiss constant to account for intermolecular interactions. The document explains that plotting magnetic susceptibility versus temperature will yield a parabolic curve, while plotting the inverse of magnetic susceptibility versus temperature will produce a straight line. Finally, it briefly discusses paramagnetism, ferromagnetism, antiferromagnetism, and ferrimagnetism in relation to magnetic susceptibility and temperature.
9 thermal strain
This document discusses the effects of temperature on materials and structures. It begins by explaining two main effects of temperature: expansion/contraction and changes in material properties. Thermal stresses can arise if a material's thermal expansion is resisted. The total strain on a material is the sum of mechanical and thermal strains. Different materials have different coefficients of thermal expansion (CTE). Temperature variations can be caused by the environment or aerodynamic heating. The temperature distribution in a structure can be determined by analyzing heat transfer through conduction, convection and radiation.

1) When speed increases, more centripetal force is needed to maintain the circular motion. If the frictional force is not enough, the car will skid off the track.
2) The steam force creates a clockwise moment on the valve, and if it is greater than the counter-clockwise moment from the weight W, the valve will open.
3) As the girl walks down, her gravitational potential energy is converted to kinetic energy and other forms of energy like heat as she stops at the bottom.
Sagcalculation 170523032311-converted
Sag is the vertical distance between the lowest point of an overhead transmission line conductor and the points of support. There are two types of sag: equal supports and unequal supports. Sag is calculated based on the span length, conductor weight, tension, and differences in support height. Maintaining proper sag is important as it determines safe tension while allowing for factors like wind, ice, and temperature changes. Too little sag causes high tension risks while too much sag compromises safety clearances.
Heat transfer
Temperature is a measure of how hot or cold an object is, with higher temperatures corresponding to faster particle motion. There are three main temperature scales: Celsius, Kelvin, and Fahrenheit. Heat is the transfer of energy between objects at different temperatures, which can occur through three processes: conduction (direct contact), convection (transfer through liquid/gas movement), and radiation (transfer through electromagnetic waves).
Heisenberg uncertainty principle
A short form presentation on heisenberg uncertainty principle.that what this principle tells us basically.
Max well boltzmann constant
The document discusses the Maxwell-Boltzmann distribution, which describes the speeds of gas molecules at a given temperature. It was first developed by Maxwell and Boltzmann based on probabilistic arguments about molecular velocities. The distribution shows the fraction of molecules moving at different speeds and depends on temperature, mass, and other factors. Graphs of the distribution illustrate how it changes for different temperatures and molecule masses. The root mean square, most probable, and average speeds can be derived from the Maxwell-Boltzmann equation.
Weiss field model
1. Weiss developed a molecular field theory to explain paramagnetism, proposing that atomic magnetic moments align due to an internal molecular field proportional to the magnetization.
2. The molecular field arises from exchange interactions between neighboring atomic moments due to the Pauli exclusion principle and Coulomb interaction.
3. The Curie-Weiss law describes the paramagnetic susceptibility above the Curie temperature, relating it inversely to temperature minus the Curie-Weiss temperature.

2nd law of motion and sig figs
The document provides instructions for a lab on Newton's Second Law of Motion. It instructs students to predict what will happen to the acceleration of a cart under different forces and masses. It lists the materials needed and measurements that will be taken, which include qualitative and quantitative observations. It also reviews key concepts like the relationships between force, mass and acceleration defined by F=ma, and how to account for significant figures in calculations and measurements.
3 e electronics 301110
The document discusses resistance and Ohm's law. It describes setting up a circuit with a resistor and power supply to take voltage and current measurements. By plotting the measurements on a graph and calculating the gradient, resistance can be determined using the equation R=V/I. Resistance is measured in Ohms and represents an object's opposition to electric current. Ohm's law states that voltage equals current times resistance. Resistors are used to control current and voltage in circuits. Power dissipated in a resistor is calculated using P=IV or P=I^2R. Resistors in series increase total resistance while resistors in parallel decrease total resistance.
3.3 notes
This document contains notes from a geometry class on proving that lines are parallel. It includes definitions of key postulates and theorems used to prove parallel lines, such as corresponding angles being congruent, alternate interior angles being congruent, and consecutive interior angles being supplementary. Examples are worked through to demonstrate these concepts. Homework problems from the textbook are assigned.
Temperature
The document discusses key concepts in temperature physics including:
1) It defines temperature as a variable that measures "hot" and "cold" and is related to the internal kinetic energy of an object or substance.
2) It provides formulas for converting between Celsius and Fahrenheit temperature scales.
3) It explains that thermal energy is the total kinetic and potential energy of all particles in a substance, and increases with higher temperature as the particles' kinetic energy increases.

2nd Law of Motion and Free Body Diagrams
The document provides instructions for a lab on Newton's Second Law of Motion. Students are told to get their lab books and materials ready. They will review a previous quiz, read about an investigation, make predictions, take notes, and conduct the investigation. The investigation involves measuring force, mass and acceleration of carts. Students will use an equation relating these variables and take quantitative measurements.
OCR Physics A Scalars and vectors
The document discusses scalars and vectors, including examples of scalar and vector quantities. It also provides examples of calculating resultant forces and velocities from multiple forces and velocities acting at angles, including using scale diagrams, Pythagoras' theorem, and resolving forces into perpendicular components.
Uncertainty
Werner Heisenberg developed the uncertainty principle, which states that the more precisely the position of a particle is determined, the less precisely its momentum can be known, and vice versa. This stems from the quantum nature of matter, where measuring devices disturb the system being measured. A thought experiment is described where observing an electron's position with a photon impacts the electron's momentum in an unpredictable way. The uncertainty principle is expressed as ΔxΔp≥h/2π, meaning the product of the uncertainties in position and momentum must be greater than or equal to Planck's constant divided by 2π.
Tension for Concurrent and Coplanar Force System | Mechanical Engineering
This document provides an overview of concurrent and coplanar force systems. It defines concurrent forces as multiple forces acting at a single point and coplanar forces as multiple forces acting in a single plane. Lami's theorem is introduced which states that for three coplanar forces in equilibrium, each force is proportional to the sine of the angle between the other two forces. Examples are given to demonstrate determining tensions in strings for systems with concurrent and coplanar forces, including strings supporting a lamp, a sphere tied to a wall, and a string passing over pulleys with attached weights.
1.1.5resistance
Resistance (R) is directly proportional to the length (l) of a material and inversely proportional to its cross-sectional area (A). Doubling the diameter of a wire increases its area by 4 times and decreases resistance. Resistance of a wire at a higher temperature (Rh) can be calculated using the formula Rh = Rc[1 + α(t2 - t1)], where Rc is the starting resistance, t1 is the starting temperature, t2 is the higher temperature, and α is the temperature coefficient. For example, copper windings with an initial resistance of 125 ohms at 20°C would have a resistance of 145 ohms at 60°C.
7-5 Newtons Third Law
1) A skydiver feels weightless while falling and accelerating due to gravity, heavier when the parachute deploys due to increased air resistance, and a normal weight at terminal velocity when acceleration equals zero.
2) Newton's Third Law states that for every action force there is an equal and opposite reaction force. Examples include a hand pushing a wall, which results in the wall pushing back on the hand, or a foot kicking a ball which causes the ball to push back on the foot.
3) Action and reaction forces do not cancel each other out, but rather act on different objects. They can cause motion, such as a swimmer pushing back on water which pushes the swimmer forward, but
Gauss’s Law

8 chapter7section1part4
This document discusses scientific principles related to mass and weight. It states that all matter consists of atoms and distinguishes between mass and weight by using appropriate instruments and units of measurement. It also introduces the law of conservation of mass, which recognizes that in a chemical reaction, the mass of the reactants equals the mass of the products. The goals are to compare mass and weight, explain the relationship between mass and inertia, and understand that mass is necessary to eventually understand the law of conservation of mass. It defines inertia as an object's tendency to resist changes in motion and notes that larger mass makes it harder to get an object moving but large mass does not necessarily mean large weight.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

It meticulously outlines several critical steps in the process, starting with the crucial task of enabling permissions, followed by the installation and configuration of WSL.
The guide then proceeds to explain how to set up the SSH service within the WSL environment, an integral part of the process. Alongside this, it also provides detailed instructions on how to modify the inbound rules of the Windows firewall to facilitate the process, ensuring that there are no connectivity issues that could potentially hinder the debugging process.
The document further emphasizes on the importance of checking the connection between the Windows and WSL environments, providing instructions on how to ensure that the connection is optimal and ready for remote debugging.
It also offers an in-depth guide on how to configure the WSL interpreter and files within the PyCharm environment. This is essential for ensuring that the debugging process is set up correctly and that the program can be run effectively within the WSL terminal.
Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.
Design and optimization of ion propulsion drone
Electric propulsion technology is widely used in many kinds of vehicles in recent years, and aircrafts are no exception. Technically, UAVs are electrically propelled but tend to produce a significant amount of noise and vibrations. Ion propulsion technology for drones is a potential solution to this problem. Ion propulsion technology is proven to be feasible in the earth’s atmosphere. The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.

Stringing chart
- 1. Define Stringing chart Stringing chart is basically a graph between Sag, Tension with Temperature. As we want low Tension and minimum sag in our conductor but that is not possible as sag is inversely proportional to tension. It is because low sag means a tight wire and high tension whereas a low tension means a loose wire and increased sag. Therefore, we make compromise between two but if the case of temperature is considered and we draw graph then that graph is called Stringing chart.
