3.2 SHAPING OF SPECIMEN
3.2.1 Lathe Machine
There are varieties of lathe machines that are available for use in the industries and engineering workshops. Although some of them may b simple or complex in operations, the main aim is to produce a given geometrical surface within certain limits of accuracy.
The main parts of the late machine are;
a. The bed
b. Tail stock
c. Head stock
d. The carriage/saddle
e. Face plate
f. The chuck
g. Cross slides
h. The tool post
i. Coolant tray
j. Gearbox
k. The centers
l. The compound slide
3.3 TENSILE STRENGTH TEST
13.3.1 The Tensometer
The general Description
The tensometer is a highly versatile testing machine. It can be used to carry out the following tests.
a) Elongation and Tensile strength
b) Shear and compressive strength
c) Hardness, ductility and plasticity
d) Flexural, stripping and tearing resistance
With the machine, there is the choice of cover 100 accessories and attachments to cover most of the varied requirements for research and development. The machine is versatile and relatively inexpensive. It has a very high cost performance rating. With overall dimensions of approximately 965mm(L) X 235mm (W) X 230mm (H) and a weight of 20kg. It can be powdered or manually operated on any small laboratory bench or table.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE 1.0   INTRODUCTION    Steel is a man-made material containing 95% of iron. The remaining constituent are small amount of element derived from the raw-material use in the making of the steel, as well as other element added to improve certain characteristics or properties of the product (Marcus, 1964).   Steel reinforcement are used generally in the form of bars of circular cross-section in concrete structure. They are like a skeleton in human body. Plain concrete without s ... Continue reading---
CHAPTER TWO - [ Total Page(s): 10 ]CHAPTER TWO2.0 LITERATURE REVIEW2.1 NIGERIAN STEEL INDUSTRY (HISTORICAL DEVELOPMENT)Planning for the Nigerian steel industry started around 1958. Many international Organizations and consulting firms had been commissioned at various times to study the feasibility of steel plants under the aegis of the Federal Ministry of Industries In 1971 an extra-ministerial agency was established by Decree to focalize efforts required to actualize a steel plant. The agency was called ‘Nigerian Steel Dev ... Continue reading---

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION AND RECOMMENDATION From the test carried out and the results obtained, the average yield strength for specimens diameter of 8mm, 10mm, 12mm, 16mm, 2Omm and 25mm were 79N/mm2, 225 N/mm2, 261 N/mm2, 277 N/mm2, 295 N/mm2 and 297 N/mm2 respectively. It was therefore observed that specimen of 8mm and 10m do not meet the BS8110 specification of 250 N/mm2 for mild steel.However, the analysis shows that the average ultimate strength obtained for the specimens of 8mm, 10mm 12mm ...
