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

ABSRACT - [ Total Page(s): 1 ]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 c ... Continue reading---
