CHAPTER ONE
1.1 INTORDUCTION
A
wheelbarrow is a simple machine which at the description of a large open
container with a wheel are two handles that one used outside to carry objects
it can also be said that it is a small hand cart with one wheel and two shafts.
The container serves as the loading point, the wheel helps its locomotion while
the two handles are two points through which the application of forces (effort)
are made possible.
Wheelbarrow
was an aftermath of the industrial revolution that took place in the Asian
country precisely China
in a millennium ago. It was purposefully invented for conveying relatively
small materials or loads from one place to the other. Apparently, from the
above one can easily deduced that wheelbarrow is one out of many types of
conveyor such as tractors, which are use in conveying load. Wheelbarrow finds
its application in agriculture where is being use in transporting both farming
materials and agricultural products. It is also use in laboratories and
industries in conveying materials, chemicals and loads in and around the
environment.
Viewing
from the point of classification of machine lever wheelbarrow can be classified
as a second-class lever. This classification is base on the fact that it has
its load in between the effort and the fulcrum. Finally, wheelbarrow is
regarded as a machine due to the fact that it makes the execution of work more
easier compare to when the work is done with bare hands. It is also regarded as
a machine from the fact that little application of and effort produces a lot of
work.

SCOPE/ OBJECTIVE OF THE PROJECT
The main
objective of this project is to provide a basic knowledge on how a strong and
reliable medium sized wheelbarrow can be fabricated in the workshop. It also
aims at reviewing the underlying literature pertaining to wheelbarrow which new
students or researches who are without proper background owning to their not
being taught at the secondary school level, can easily consult.
Against this
backdrop the project has looked at its subject matter from the most basic
perspective so as to enable new students in the beneficiaries.
This
experimental work will cover discussions and write up on the literature, mode
of operation, origin, types and the processes involved in the fabrication
of a medium size wheelbarrow.
