ABSTRACT This write up is a detail of the process and formulation of plan for the physical realization of the construction of a refrigerator. It is divided into chapter, which discussed extensively the practical refrigeration cycle with full attention given to design factors, working principle and choice of material. The method used in construction, assembly and arriving at knowing the safety requirements were not left out. TABLE OF CONTENT Title page Letter of Transmitta...
TABLE OF CONTENT Definition of Bearing Various types of Bearing and Features Classification of bearing Uses of types of bearing Criteria for bearing selectio DEFINITION OF BEARING A bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle.
TABLE OF CONTENT Introduction Brake System Types of Brake System Applications of Brake System Performance Parameters of Brake System INTRODUCTION A brake is a device which inhibits motion. Its opposite component is a clutch. The rest of this article is dedicated to various types of vehicular brakes. Most commonly brakes use friction to convert kinetic energy into heat, though other methods of energy conversion may be employed. For example regenerative braking converts much of the energy to e...

ABSTRACT This write up focuses attention on a detailed report and account on the process of construction and formulation of plan for the actual and physical realization of the construction of the project work captioned fabrication and construction of a mobile cooling system. The report is therefore divided into chapters and each chapter discussed extensively such that an illiterate refrigerator mechanic who read and comprehends the report can easily carryout the construction of refrigerator...
Company background and overview Anbessa City Bus Service Enterprise is the largest City Public Transportation Company in Ethiopia established immediately after the Italian invasion in 1943 by collecting old vehicles and garage equipment from the invader. At the time its name was Public Transport and guided by Italians and other foreigners. In 1952, it was organized in to a share company by getting legal entity from the government. At that particular year the enterprise had only 10 buses t...
Machining: Sintered parts do have some porosity and it is, therefore, necessary to differentiate their machining behaviour from those of fully dense wrought products. The major differences are, as follows: (i) when a porous metal is machined, the depth of work hardening is more important than for the wrought metal, as in case of former, pores create stress concentration. (ii) The temperature at the tool end causes oxidation of the pore surface. (iii) The surface porosity enhances tool vibra...
ABSTRACT The report beamed at relying the student intense knowledge and skill acquired during my industrial training attachment of the Nigeria Railway Corporation Enugu. it is a well articulated report that gives a comprehensive hand-or-the job report of the student and each chapters from machine shop, smith, foundry and the react gives an indepth. coverage of the corporation work nature.

INTRODUCTION Planned maintenance apart from programming inspection, should include monitoring, logging, periodic checks and tests of system as to guarantee correct day-today hitch free functioning and control of “closed circuit” water systems to maintain trouble-free operations.This first requirement for any maintenance system planned or otherwise is to compile an inventory of all plants and equipment to be maintained. Besides, additional information must be readily obtained from the manu...
INTRODUCTION Nigeria is an agricultural nation. Melon (Citrullus Vulgaris) is widely cultivated in Nigeria, among other seedlings during the planting season yearly. Several tones of the melon seeds are gathered each harvesting period but only very low percentage of the total harvest are dried by atmospheric draught and bagged for storage. High percentage waste is encored due to lack of good processing and storage facilities.Melon when properly processed yields a lot of by-products, which co...
ABSTRACT This Machine is design and fabricate as a prerequisite for the award of a Higher National Diploma. We sketch different designs which after consideration of many factors like the machine efficiency, the cost of materials e.t.c before we finally embark on this machine.The machine major component are the shaft, the inner barrel, the outer barrel, the conveyor, the tray etc.The machine is build with very strong and well selected materials which enhances the performance of the machine. ...
ABSTRACT The project work titled Design and construction of a metal detector. When fully design and implemented would be able to detect any metallic material that is passing or coming close. This function would serve as a security check for dangerous metallic material as an alarm. Going by the sophisticated means of armed rubbers adopt these days in the breaking into bank supermarkets offices and highly secured area. No security system will be optimised or complete without the installation of...
ABSTRACT This research is centered on the design and fabrication of copula furnace and atomizer for the production aluminium powder metal with the available material.0.4kg of refined coke was chosen as the basis for material and energy balance calculations and the design calculations performed from whose values are used to produce the design drawings.Mild steel was used for the internal linings of the furnace casing while other materials were selected based on functionality, durability, cost ...
ABSTRACTOil spillage which can simply be referred to as the release of oil into the environment (land or water) either through a deliberate act, accident or as a result of equipment failure indeed has an alarming effect on the affected communities due to the fact that it either renders the environmentuseless or sometimes take a longer time for the affected area to have a natural process of attenuation.In addition, having given the necessary compensation to the affected communities in line wit...
ABSTRACTThe rapid increase in energy consumption particularly in the past several decades has raised fears of exhausting the globe’s reserves of petroleum and other resources in the near future. The huge consumption of fossil fuels has caused visible damage to the environment in various forms. Approximately 90% of our energy consumption comes from fossil fuels. Due to industrializations and population growth our economy and technologies today largely depend upon natural resources, which are...
