Today plastic is an industry -greater than steel and aluminum combined. Plastic probably have one of the most spectacular growth history among engineering materials. Within relatively short time of their inception, these versatile materials began to replace metals and woods in variety of applications. Plastics is a product that was invented in early 20 century and now at the dawn of the century disposal of plastic is of great significance. They have taken over from other materials as the material of choice in many sectors of industry and life. ....etc

PLASTICS EXPLOSION
INTRODUCTION
Synthetic polymers are often referred to as plastics, such as the well-known polyethylene and nylon. However, most of them can be classified in at least three main categories: thermoplastics, thermosets and elastomers.
Man-made polymers are used in a bewildering array of applications: food packaging, films, fibers, tubing, pipes, etc. The personal care industry also uses polymers to aid in texture of products, binding, and moisture retention (e.g. in hair gel and conditioners).

electricity-conducting plastics
abstract
ScienceDaily (Apr. 3, 2010) A new technique developed by Princeton University engineers for producing electricity-conducting plastics could dramatically lower the cost of manufacturing solar panels.
By overcoming technical hurdles to producing plastics that are translucent, malleable and able to conduct electricity, the researchers have opened the door to broader use of the materials in a wide range of electrical devices. ....etc

Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its excellent conductivity, low weight and low cost. The center strand, or strands is/are of steel for additional strength to help support the weight of the conductor. Steel is higher strength than aluminium which allows for increased mechanical tension to be applied on the conductor. Steel also has lower elastic and inelastic deformation (p ....etc

DESIGN, FABRICATION AND PERFORMANCE EVALUATION OF GARDEN TILLER

ABSTRACT
In order to meet the food requirements of the growing population and rapid industrialization, modernization of agriculture is inescapable. Mechanization enables the conservation of inputs through precision in metering ensuring better distribution, reducing quantity needed for better response and prevention of losses or wastage of inputs applied. Mechanization reduces unit cost of production through higher productivity and input conservation.

History of Polymer and Plastics

History of Plastics and Polymers

Plastics are polymers. What is a polymer? The most simple definition of a polymer is something made of many units. Think of a polymer as a chain. Each page link of the chain is the mer or basic unit that is made of carbon, hydrogen, oxygen, and/or silicon. To make the chain, many links or mers are hooked or polymerized together. Polymerization can be demonstrated by linking strips of construction paper together to make paper garlands or hook ....etc

TYPICAL LAYERS OF A FLEXIBLE PAVEMENT Base course The base course is the layer of material immediately beneath the surface of binder course and it provides additional load distribution and contributes to the sub-surface drainage It may be composed of crushed stone, crushed slag, and other untreated or stabilized materials. Sub-Base course The sub-base course is the layer of material beneath the base course and the primary functions are to provide structural support, improve drainage, and reduce the intrusion of fines from the sub-grade in t ....etc
