ABSTRACT
Bookshelf, a Mechanical
arrangement of materials were documents are stored, it could be made with metal
or wood. But this one is fabricated with
metal.
The type of metal used in the
fabrication is mild steel and square baluters.
The undismountable bookshelf
which has five partitions and four compartment under went many process namely,
the drawing and the dimensioning of the bookshelf, needed materials, the
marking out and cutting of the materials, welding, smoothing and filling of the
work, then finally painting.
Actually our dreams has come
through in fabrication of metal shelf that will be economically and at the same
time meet up with the needed standard despite the subsidized rate.

INTRODUCTION
A
bookshelf is an invention with compartments and partitions where books and
files are packed in offices, libraries and even homes.
A bookshelf can be wooden,
metallic or even glassed. They could
also be dismountable metallic and indismountable.
In our project, we decide to
design and fabricate an undismountable metallic bookshelf. Certain factors were considered before
embarking on this project.
An undismountable metallic
bookshelf, have a longer life span and serves its purpose better than a wooden
bookshelf. Also lose of parts of many
dismountable bookshelf held us into opting for the one with its pant in tact.
Nevertheless, the need for preservation
of books to enhance researches and studies purpose has brought about the
construction of bookshelves for offices, libraries and homes. Thus, these protects the books from been
easily destroyed by ants, rats, and from children.
And
it also enhances systematic arrangement of books for easy reference of
location.
In the fabrication, the frame
first erected before making the sides and the partitions with the steel
material. The mass and volume of the
books to be contained by the partitions were considered before they were
erected; so certain experiments were carried out which will be further
discussed in the report.

SIDE
The
side of the bookshelf are shown in fig 1a.
It is made up the square pipe frame and the mild steel plate material
welded to it. Each side is specially
designed to act as support in carrying the load under any stress. the load dispersed on the system. The sides measures and tacted at an angle of
900 to each other giving the system a more rigid frame work. The sides measures.
