ABSTRACT

In our society today reading and writing has taken its roll as a way of measuring human knowledge. Knowledge could only be obtain successively by the use of books for research but unfortunately because of hard time, books have because very expensive.
This has called for preservation of books already purchased, whether in the public library school or in the house hold so that it can use for future reference. These could only be done by stocking books systematically in a bookshelf where by it can be free from rat, insects and other thing that could destroy books.
Our own contribution towards this development is the design and manufacture of a bookshelf that will be economically cheap and at the same time meet up its demands.
Bookshelf could be made with metals or wood and they could be attached against the wall or they could be made standing on the floor. Our bookshelf shall be of the metal type standing on the floor.

CHAPTER ONE
1.1INTRODUCTION
A bookshelf is a device with partitions use for the purpose of self-guarding books and files in offices, libraries and at homes.
A bookshelf can be wooden, metal or glass. They could also be design in such a way that they could be dismountable or undismountable. In our project, we decided to design and fabricate on undismountable metallic bookshelf.
Amoung they bookshelves, the undismountable metallic bookshelf has the longest lift span because of its rigidity, quantity of material and it ability to with stand heavy loads. In other words, the constant loosening and coupling of the component parts which lead to the weakness of the bolt and nut, thus subject the shelf to vibration.
Our project being the undismountable bookshelf was fabricated with variety of material. The types of materials involved are mild steel square pipes (25mm x 25mm) mild steel sheet metal, metals nets (wire gauze) etc. in this, the square pipes were used in the fabrication of the frame work while the mild steel sheets were use to cover the partitions and outside bodies of the shelf and the metal nets (wire gauze) where used in the creating of the two doors.
The essence of creating steel fame work with pipes is for it to withstand the stress that will be develop due to the weight of they material and loads or each partition.
In fabrication, the frame was first erected before covering with the mild steel sheet. The mass and volume of the book to be contained by each partition were considered before they were erected, so certain experiment were carried out which will be discusses in detail in this report.
1.2DESCRIPTION OF THE METAL BOOK SHELF
The metal bookshelf as shown in fig.1.1 is made up of the following parts and components.
(i)                The frame work
(ii)             The side
(iii)           The back
(iv)           The door
(v)             The top
(vi)           The stand
(vii)        The partitions
