THE BACK
The back of the book shelf is shown in the figure provided (fig2). It
is made up of the same metallic mild steel used for the side, it is
welded to the square pipe frame and 6the sides at angle of 90o. its
measurement is 1200mm.
With a thicken of 3mm.
Since the back serves as a cover sort of to the system, a metallic
sheet with a higher this chime in chosen so as to withstand rush,
corrosion, intensity and weight of the system that is why one choose a
material of 3mm thicken.
THE PARTITIONS
Our bookrack was
designed to have 3 partitions be on to able to contain large number of
books. The partitions is as shown in the figure measuring 5 fit length,
4ft width and 2ft deep. The material used for the partition in a mild
steel materials. This is so because each portion is designed to carry a
maximum load of at a time.
This partition is added to the
square bar frame side and back of the bookrack making a more rigid frame
workout of the system.
The volume of the partition and the arenas calculated as follow:
THE FRAME
The
frame is the skeleton of the whole system, it is made of 1inch square
pipe. This frame was first erected together by welding, before the
sheets for the sides, back and partition where attacked to it.
The
frame was designed to withstand the stress that will be exerted on it by
both the sheets and the load. The tensile stress that will be exerted
on the frame was calculated.
THE DOORS
The doors is of
two parts the upper poin6t and the lower part, the upper part encloses
the first two partition of the upper chamber which is of guaze. The
guaze is also welded to it.
They lower part which encloses the last
partition of the shelf, this door is made of steel, sheet and frame
which is welded on to a hinge to help in open and closing.
The door also has a handle to aid in the movement.
The doors were designed for measure sayly of the book from rodents and tempering by introduce.

ABSRACT - [ Total Page(s): 1 ]Knowledge could only be obtained successfully by the use of book for research but unfortunately because of hard times, books have become very expensive. This is called for presentation of books already purchased whether in the library or on the household so that it can be used by the future generation. There could only be done by stacking books systematically on a book rack where by it can be file from rats and other insects that could blestroy books.Our aim contribution to this development ...
