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

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 ....etc

COMMON SYNTHETIC PLASTICS

INRODUCTION
Plastic molecules are made of long chains of repeating units called monomers. The atoms that make up a plasticâ„¢s monomers and the arrangement of the monomers within the molecule both determine many of the plasticâ„¢s properties. Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles by the application of heat and pressure ,it is used as plastic.
Synthetic polymers are often referred to as plastics, such as the ....etc

Introduction

Plastics today are larger serving as substitute material in the field of tooling and prototype parts but are being used as engineering materials in their own lights and in many applications, they are doing better job then any other material could do, some authorities claim that the rapid advancement of plastic tooling would have been impossible without the versatility of the epoxyresin.
Plastic tooling offers several advantages over conventional metal tooling. These includes:


1. Lowest cost
2. Less time.
3. Light weig ....etc

RADAR AND SYNTHETIC APERTURE RADAR BASICS
PRINCIPLES OF RADAR
HOW DOES RADAR WORK?
• RADAR = Radio Detection And Ranging
• Since radar pulses propagate at the speed of light, the difference to the “target” is proportional to the time it takes between the transmit event and reception of the radar echo
PRINCIPLES OF IMAGING RADAR
