Presentation Moment Distribution Method

The moment distribution method is a structural analysis method for statically indeterminate beams and frames developed by Hardy Cross. It was published in 1930 in an ASCE journal.[1] The method only accounts for flexural effects and ignores axial and shear effects. From the 1930s until computers began to be widely used in the design and analysis of structures, the moment distribution method was the most widely practiced method.

Statically indeterminate beam moment distribution method

The method of moment distribution is this:
Imagine all joints in the structure held so that they cannot rotate and compute the moments at the ends of the member for this condition.
At each joint distribute the unbalanced fixed-end moment among the connecting members in proportion to the constant for each member defined as "stiffness“.
Multiply the moment distributed to each member at a joint by the carry-over factor at that end of the member and set this product at the other end of the member;
Distribute these moments just "carried over“.
Repeat the process until the moments to be carried over are small enough to be neglected.
Add all moments -- fixed-end moments, distributed moments, moments carried over -- at each end of each member to obtain the true moment at the end.

Calculating truss forces

- A truss is a structure composed of slender members joined at their endpoints. Trusses use triangular shapes that retain their form even when supports are removed.
- To solve for forces in a truss, assumptions are made that members are straight, loads apply at joints, joints are frictionless pins, members have no weight, and members experience only tension or compression.
- The method of joints is used to solve each joint by summing forces and moments. Free body diagrams are drawn and updated as member forces are solved sequentially.
- This process begins at a simply supported joint and uses trigonometry and equilibrium equations to calculate member forces throughout the truss.

L10 slope deflection method for the analysis of indeterminate

The slope deflection method is used to analyze indeterminate structures. It uses the principle of superposition to consider the moments developed at each support of a continuous beam due to applied loads and displacements. The method establishes load-displacement relationships and develops slope-deflection equations to solve for member forces and displacements. Key steps include assuming fixed ends to determine initial end moments, releasing one end to calculate its moment-rotation relationship, and developing equations relating member end moments to nodal displacements.

Slope deflection method

This document describes the slope deflection method for analyzing structures. It was first presented in 1915 as a way to analyze frames by treating joints as rigid units that rotate. The method assumes deformations are from bending only and members have constant sections. Unknowns are joint rotations rather than member forces. It can be used for determinate and indeterminate structures. The procedure involves writing member end moments in terms of stiffness and rotations, then establishing equilibrium equations at each joint to solve for rotations. Rotations are back-substituted to find member moments. The method is suitable for computerization due to its general nature.

2) The influence line is drawn by plotting the value of the function versus load position.

They can be constructed using either the static method by placing a load at different positions, or the virtual displacement method which imagines cutting the structure at a point. ILDs help determine maximum effects and where to position loads to cause these maxima, simplifying analysis of moving loads.

Lecture 4 (cen 309) IUBAT

An influence line shows the variation of shear, moment, reaction, or member stress in a structure due to a moving unit load. It is constructed by plotting the value of the specific function as a unit load is moved along the structure.
Influence lines for determinate structures are always straight lines. To construct an influence line, the effect of a unit load is observed as it is moved along the span, and the controlling ordinates are calculated and plotted.
The Muller-Breslau principle states that the ordinates of an influence line are proportional to the deflected shape of the structure if the capacity for a specific force is removed and an equivalent displacement is introduced.

Presentation on bending moment.10.01.03.010

This document provides information about bending moment in a presentation on pre-stress concrete design. It defines bending moment as a measure of bending forces acting on a beam, measured in terms of force and distance. Shear and moment diagrams can show the bending moment and shear force functions along a beam. Bending moment at a section is the sum of moments of all forces on one side and can be represented in a bending moment diagram. Positive bending moment results in tension on the bottom fibers while negative bending moment results in compression. Bending moment is measured in units of Newton-meters or foot-pounds. Simple bending theory makes assumptions about beam properties and behavior.

Center of gravity

The document discusses the concept of center of gravity and how it relates to an object's stability. It defines center of gravity as the point where an object's entire weight seems to act and explains that an object's stability depends on the position of its center of gravity relative to its base. Specifically, an object will be stable if tilting moves the center of gravity higher within the base, unstable if tilting lowers it outside the base, and neutrally stable if tilting does not change the height. Real-life examples like buses and lamps are designed with low, broad bases to lower the center of gravity and increase stability.

Rainfall intensity duration frequency curve statistical analysis and modeling...

Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

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.

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.

Embedded machine learning-based road conditions and driving behavior monitoring

Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Gas agency management system project report.pdf

The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.
