static and dynamic balance
this ppt file is one of my report in my college years... you can use this as reference though,,,, I made this with some animations
Vibration Monitoring
1) Unbalance, misalignment, looseness and resonance are some of the key machinery faults that cause vibration. Unbalance produces a 1X signal while misalignment produces both 1X and 2X signals.
2) Rolling element bearings produce characteristic frequencies including ball pass frequencies that can indicate inner or outer race damage. Journal bearings are more damped while rolling element bearings produce clearer fault frequencies.
3) Resonance occurs when the machine's operating speed matches its natural frequency, greatly increasing vibration. It requires additional testing like run up/coast down to diagnose.
Static Force Analysis
The document discusses static force analysis and equilibrium of mechanisms. It covers topics like static equilibrium, equilibrium of two and three force members, members with two forces and torque, free body diagrams, and the principle of virtual work. Examples of static force analysis of four bar and slider-crank mechanisms are presented. Methods to determine the forces and torques required for static equilibrium are demonstrated through graphical techniques like force triangles and the principle of virtual work.
Balancing of rotating masses
Unit 4- balancing of rotating masses, Dynamics of machines of VTU Syllabus prepared by Hareesha N Gowda, Asst. Prof, Dayananda Sagar College of Engg, Blore. Please write to hareeshang@gmail.com for suggestions and criticisms.

This document discusses induction motor faults. It begins by describing the construction of induction motors, including the stator, rotor, and other parts. It then discusses various types of faults that can occur, including broken rotor bars, rotor mass unbalance, stator faults, single phasing, crawling, and bearing faults. The causes and effects of some key faults are described in more detail, such as broken rotor bars which can be caused by manufacturing defects or thermal/mechanical stresses and produce sideband frequencies in the stator current signature. Rotor mass unbalance is also discussed as causing air-gap eccentricity.
Rapid prototyping
Rapid prototyping technologies allow engineers to create physical prototypes of designs prior to full production. The document discusses the rapid prototyping process which involves:
1. Creating a CAD model and converting it to STL format.
2. Slicing the STL file into thin layers and constructing the prototype layer-by-layer using different techniques like stereolithography, selective laser sintering, or fused deposition modeling.
3. Post-processing the prototype by removing supports, cleaning, and finishing the surface.
Specific rapid prototyping methods like stereolithography, selective laser sintering, and fused deposition modeling are described in detail. The document also discusses applications and limitations of rapid
Usm
The document discusses ultrasonic machining (USM), a non-traditional machining process that uses ultrasonic vibrations to remove hard and brittle materials. It describes how USM works, including that an oscillating tool vibrates at ultrasonic frequencies (18-20 kHz), using an abrasive slurry to chip fine particles from the workpiece. The key components of a USM system are also outlined, including the magnetostrictor, concentrator, tool, and slurry feeding arrangement. Factors that influence the USM process and material removal rate are then examined, such as amplitude of tool vibration, abrasive grain size, concentration/hardness of the slurry, impact hardness of the workpiece
Micro mach
This document discusses recent trends in non-conventional micromachining techniques. It describes several methods such as electrochemical micro-machining (EMM), micro-electrodischarge machining (MEDM), laser micro-machining (LMM), ultrasonic micro-machining (USM), and chemical micro-machining (CMM). For each method, it explains the basic principles, micro-machining processes, applications for micro components, and potential for future development at the nanoscale. The document also explores emerging nanomachining techniques using tools like atomic force microscopes and various top-down and bottom-up fabrication processes.
Mechanical
The document outlines the specifications for the Fundamentals of Engineering (FE) Mechanical CBT exam, including the following key details:
- The exam is a 6-hour computer-based test containing 110 multiple-choice questions to be completed within that time frame.
- The exam covers 15 subject areas related to mechanical engineering, with the number of questions in each subtopic range specified.
- Subject areas include mathematics, statistics, mechanics, thermodynamics, fluid mechanics, materials properties, heat transfer, and mechanical design and analysis.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

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.

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.

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.
