V-belts are used to transmit power between pulleys in factories and workshops. They are made of fabric, cords, and rubber molded into a trapezoidal shape to fit into the V-grooved pulleys. The belts grip the pulleys through a wedging action caused by the 30-40 degree V-groove. Clearance is provided at the bottom of the groove to prevent wear from making the groove narrower. The driving tension ratio between pulleys depends on factors like the groove angle and coefficient of friction between the belt and groove.

This document describes a mini project report on a rope brake dynamometer. A rope brake dynamometer consists of a rope wrapped around a pulley connected to the shaft of an engine. One end of the rope supports a dead weight and the other is attached to a spring balance. It works by absorbing the torque produced by the engine through friction between the rope and pulley. The difference between the tensions in the two sides of the rope is used to calculate the braking torque and absorbed power of the engine. The report provides details on the construction, working principle and applications of a rope brake dynamometer.

Leaf springs are made of beams with uniform strength and are commonly used in automobiles. They consist of multiple leafs stacked together to form a cantilever beam. This distributes the load from the road across the leaves. Stress and deflection analyses show that the stress in the master leaf is 50% higher than in the graduated leaves. However, giving the master leaf a curvature through residual stresses can equalize the stresses across leaves and increase the total load capacity. Equations are derived relating load shared, stresses developed, and maximum deflection to the number and dimensions of leaves.

A belt drive uses a looped strip of flexible material called a belt to mechanically link two or more rotating shafts. Belts are looped over pulleys to transmit power efficiently between shafts. Belts can drive pulleys in the same direction in an open belt drive, or in opposite directions in a crossed belt drive. Belts transmit power simply and economically over variable distances between non-parallel shafts while absorbing shock and reducing noise and vibration. However, belt slip and stretch can vary the speed ratio from the pulley diameter ratio.
Wire ropes are made of strands of twisted steel wires wrapped around a core. They are used to transmit power over long distances in applications like elevators, cranes, and bridges. Wire ropes have advantages like being lighter, more reliable, and durable. They are classified based on the direction of twist of the wires and strands. Design considerations for wire ropes include selecting the type based on application, calculating design load and rope diameter, and ensuring stresses do not exceed the rope's ultimate strength. Sample problems demonstrate designing a wire rope for a mine hoist and selecting a rope to lift debris from a well.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
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.
Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
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.
