ABSTRACT
The fabrication of a standard wheel barrow is a very cheap and easy to construct it the right materials are selected and also if the right sequence of fabrication is observed. However, in the construction of a standard wheel barrow, the amount of load the materials can withstand when considered will also determine the type of type of material, properly and the liberation to be encountered. In conclusion, some precautional and maintenance measures should be taken are off when making use of a mechanical wheelbarrow. To ensure the safety of the operator and also to increase the life span of the system. Some of these measures include.
- Pump the tyre to the required gauge
- Lubricate the bearing and other frictional parts
- The handle should be lifted up and clear its stand before moving
- Bearing should be changed when faulty
- The nut and bolt should always be well light.
CHAPTER ONE
1.1 INTRODUCTION 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.
1.2 SCOPE/ OBJECTIVE OF THE PROJECTThe 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.
