increased load handling‚ longer lifetimes and corrosion resistance to name but a few. Engines in particular have received much attention. The engine and its components alone contribute to 15 percent of the total frictional losses in the vehicle. Aluminium alloys have more recently been preferred to cast iron to reduce the overall weight of the car‚ to improve fuel efficiency and road performance. However‚ as engine technology continues to develop‚ and more power is demanded from the unit‚ so the severity

A mirror is an object that reflects light in a way that preserves much of its original quality subsequent to its contact with the mirror. Some mirrors also filter out some wavelengths‚ while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror‚ which has a flat surface. Curved mirrors are also used

INTRODUCTION Post independence‚ steel industry in India came under the regulatory framework of Government of India‚ which stipulated that steel industry be reserved under the public sector. It also stipulated that capacity creation and enhancement would require licensing‚ and that pricing and distribution of steel would be subject to govt. control. Nationalization of TISCO‚ that existed from before independence could not be carried out due to popular pressure[3]. Economic reforms were started

ELECTRONEGATIVITY This page explains what electronegativity is‚ and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegativity in an organic chemistry context‚ you will find a link at the bottom of this page. What is electronegativity Definition Electronegativity is a measure of the tendency of an atom to attract a bonding pair

REPAIRS‚ REHABILITATION AND RETRO-FITTING | Significance of Ferrocement repairs | After‚ we in India‚ started manufacture of concrete in years 1930’s‚ the negative aspect of concrete started showing after sometime as below:- | - Deterioration due to poor workmanship‚ particularly high water content and corrosion of reinforcement and R.C.C. Technology being new. | - Leakages in concrete due to rain water as well as in water retaining structures | This menace become conspicuous after construction

BRIEF HISTORY The first people that lived in Canada were natives‚ primarily the Inuit (Eskimo). The Norse explorer Leif Eriksson may have reached the shores of Canada in 1000‚ but the actual history of the white man in the country actually began in 1497. This was when “John Cabot‚ an Italian in the service of Henry VII of England‚ reached Newfoundland or Nova Scotia. Canada was taken for France in 1534 by Jacques Cartier. France’s colonization efforts were not very successful‚ but French explorers

Solid Mechanics Lab Report Measurement of Young’s Modulus Sherin Joseph 00549618 Measurement of Young’s Modulus of Aluminium using Cantilever loading Abstract The Young’s modulus of Aluminium was calculated using the measurements of the cantilever deflections. A beam of aluminium was clamped on one end and the other end was loaded with different weights‚ ranging from 1 to 15N. The deflection was then measured using a dial gauge. The slope of a load (abscissa) vs. deflection (ordinate)
