MECHANICAL ENGINEERING PROJECT TOPICS AND MATERIALS

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 under little guidance and supervision.

This project is designed to make the students utilize as many theoretical and practical concept as have been instructed in alstron to mechanical engineering workshop technology. Students are expected to learn and apply concepts, principles about energy specially the conversions of electrical energy to thermal energy, conduction and conventional heat transfer etc.

This project is concern about the construction of an electrical stove with three oven apartment is described in his project. It was carried out in order to solve the problem often encounter in cooking and drying and at the same time finding an alternative means to replace the use of kerosene and gas for cooking and drying which are often not available due to scarcity of these products, however, the project students have employed the use of electricity which is rending available.

The construction of a two-face gas burner as a project topic that we embark upon become necessary as a way of way of putting into application the engineering and technological knowledge acquired so far. It is a starting point of actualizing a functional technology in the country. Irrespective of the fact that there are several breads of gas burners in the market, especially the ones imported, we deemed it necessary to work further on it as a way of modifying the brand with cast not left out in such modification.

Man’s imp act on global environment system especially in the area of dust extraction is now at a scale where it is disrupting. These dust extractors varies in major ways. The environmental degration is, in turn contributing to health threat in this part of the globe. Unfortunately most factories, workshops which suppose to posses these machines for dust extractions a re not having them thereby making dust a very dangerous threat to man.

The design and fabrication of a reciprocating nail gasket is a new innovation in technology. The one in existence is manually operated. In which a punch that is adjacent to a die is mounted to the handle which is attached to the shaft. A helical spring that is incorporated to the shaft of the punch, helps the handle return to its initial position, which makes the machines tedious and stressful to operate. When the handle is pulled down from its initial position, the punch passes through the die that is placed vertically adjacent to the punch thereby blanking out the felt materials.

Solar energy is the light which come in form of electromagnetic radiation. Electromagnetic radition is a wave like phenomenon that move energy across distance. Solar energy is the most abundant continuing source of energy available to the human race. Solar energy is not being used as primary sources of fuel energy but a large research and development effort has being underway to develop economical systems to harness solar energy as a major source of energy particularly for the heating and cooling of buildings.

This work is aimed at designing and fabricating a spin dryer which can be used in drying spent grains after brewing. This will no doubt save considerable human labours and time wastage involved in conventional method of drying the spent grains by spreading on the ground. It also saves as a means of employments for our teaming population. This machine was designed after due consideration of its ease of production, maintenance and servicing.

This project entails the systematic approach used by the authors to design and construct a submarine hull which is watertight to at least a depth of one meter. A NACA 6- series airfoil shape was used because of its emphasis on maximizing laminar flow, owing to the fact that resistance can be reduced by maintaining a laminar boundary layer. Included is detailed literature research acting as a basis of the design, results from resistance test and other relevant information. Results obtained from final calculation showed L: D ratio as 5.0 and the drag at 2.57m/s to be 354.022N.

To achieve this preliminary experiment was carried out to determine the optimum speed of this machine various design alternatives for achieving the design solution were synthesized and a choice of an economic method which would satisfy the objective was made. Based on the principles guiding the performance of the machine, the dimensions and sizes of the various components were established.
