Metal Matrix Composites (MMC’s) have evoked a keen interest in recent times for potential applications. Composite materials like Particle-reinforced Aluminium Silicon carbide (Al/SiC) Metal-Matrix Composite is gradually becoming very important materials in manufacturing industries e.g. aerospace, automotive and automobile industries due… Continue Reading
Steel is arguably the world’s most ‘advanced” material. It is a very versatile material with a wide range of attractive properties which can be produced at a very competitive cost. It has a diverse range of applications, and is second only to concrete in its annual production tonnage. Steel is not a new invention which leads to a… Continue Reading
INTRODUCTION The rapid development in the automobile and aircraft industries requires among other things, the integration of unique materials for design purposes that reduce fuel consumption to preserve the dwindling hydrocarbon resources without compromising other attributes such as safety, performance, recyclability and cost. Similarly, the… Continue Reading
In this project (3) alternative design solutions were considered for the locally made electric run. The authors utilize the available local raw demerits of each alternative with respect to the considered group were discussed and the solutions of the alternative that best satisfied the limitations was selected for production. Material… Continue Reading

In the mechanical engineering department of institute of management and technology there are many machines but it is not all that is functioning well. This may airless as a result of lack of maintenance which is a prove in the breakdown of the air conditioner. The quality and effectiveness of materials were mated very well as referred… Continue Reading
Rapid prototyping is widely used to reduce time to market in product design and development. Today's systems are used by engineers to better understand and communicate their product designs as well as to make rapid tooling to manufacture those products. Computer Numerically Controlled (CNC) milling machines are part of this technology.… Continue Reading
This thesis aims to explore the theories and techniques behind procedures of developing a high precision cost-effective mini CNC milling machine. This newly designed machine tool can be widely used in electrical and medical industry for making small parts and engraving small features. Various structures were explored and compared… Continue Reading
The need for an authentic and reliable report relating to the repairs and rehabilitation of a faulty air conditioner is inevitable. The fact that many people use the air conditioner to cool the temperature in their respective home and offices make its maintenance a top priority to every individual in order to avoid huge expenditure in… Continue Reading
The concept of this project is to actualize a practical way of paint production using a locally design mixing machine which is design to meet a low cost and high standard paint. The project cut across all forms of engineering, such as mechanical machine design of a simple industrial mixer, which is driven by an electrically… Continue Reading
This study has evaluated the effectiveness of metallic materials as chill in sand casting of aluminium alloy. Four plates of dimension 165mm x 80mm x10mm were cast using sand mould. Steel, copper and brass chills in form of cylindrical bar of geometry 7mm in diameter and 50mm long were inserted, side by side at regular intervals of 30mm… Continue Reading
The performance of the oils selected in this work was tested for considering Viscosity, Viscosity Index, Density, Flash Point, Pour Point, and Carbon Residue. The most important of all the properties which makes the oil protect against wear is viscosity that helps to reduce friction between moving parts in the engine. The Viscosities of… Continue Reading
Theaim of this study is to investigate why the implementation of Unity and Efficiency in Production(UEP)is not yielding the expected results in PAN. The overall operations, production and sales are still on the low trend.This survey examined how the adaptation of UEP tools and the level of functions integration relate to the overall… Continue Reading
The study examined the effects of faulty design and construction on the maintenance of building. A survey of randomly selected samples of 20 builders and 15 architects were conducted. Questionnaires were used to collect data from Architects and Builders. The survey included 11 groups of defects and sub defects in each groups. The… Continue Reading
This research centers on the design, development and testing of a motorizedjuiceextractor fabricated using locally-available materials. The machine is made essentially of two basic compartments: the chopping compartment and the juice extracting compartment. Other components include feeding hoppers, top cover, auger conveyor housed in a… Continue Reading
Five coal samples from Odagbo (Kogi State), Owukpa (Benue State), Ezimo (Enugu State), Amansiodo (Enugu State) and Inyi (Enugu State) weresubjected to proximate analysis, ultimate analysis, calorific value determination, petrographic and thermogravimetric analysis to determine their suitability for power generation. Tests were carried out… Continue Reading
The physical presence of the oil industry in Nigeria is so large and has resulted in a lot of activities in the upstream sector which has deleterious effects on ecosystem stability and local biodiversity – which the peoples‘ livelihoods depend upon. This research provides an overview of environmental issues in the oil and gas industry… Continue Reading
A solar ovenis a device that converts solar energy into useful heat in a confined space (oven chamber) which can be utilised for cooking and baking purposes.The oven consists of plane reflectors to concentrate the solar radiation on the collector.The heat gain is maximum if the collector and reflectors are continuously adjusted such… Continue Reading
Thermal electrical power generation is one of the major methods used in Egbin thermal station. Due to inconsistency and failure in the power supply in Nigeria, there is a need for a proper operation and maintenance schedule strategy of the various kinds of power plants accessories so as to facilitate their efficiencies and functionality.… Continue Reading
Knowledge could only be obtained successfully by the use of book for research but unfortunately because of hard times, books have become very expensive. This is called for presentation of books already purchased whether in the library or on the household so that it can be used by the future generation. There could only be done by… Continue Reading
