Impact Test is conducted to study the toughness of some specimens of steel. Toughness is the measure of the ability of a material to absorb energy up to fracture. It has been discovered that the larger the area under a material’s stress-strain curve‚ the tougher it is. Therefore a more ductile material is tougher. An impact test is used to ascertain the fracture characteristics of the material‚ and it merely offers a relative sense of a material’s toughness. 2. APPARATUS (i) Vicker’s Hardness

In the sport of baseball‚. an above average player is seen when their batting average is above .300‚ in other words‚ getting a hit 3 out of every 10 at-bats. Above is considered a great player‚ and below is a below-average player. The same can be said in school as in the sport of baseball. A majority will be considered average‚ but you have the select few that fall on either side of the spectrum‚ almost as a bell curve. I am lucky enough to be on the right side‚ as an above average person in all

In MS-13 it is very important for them to be able to communicate without using words or at least words that would make them look suspicious. To avoid being caught they use symbols to communicate to one another. Symbols are a mark or character used as a conventional representation of an object‚ function‚ or process . Tagging is very common in gangs they use them to mark territories. They do this to warn other gangs from entering their territory or to mark new territory they have taken from rival

CASE: 1 GEORGE DAVID 1. What makes George David such a highly regarded manager? * Best Educated Manpower One of George David’s most notable good deeds was to set up a landmark of $60 million per year employee scholarship program in 1996. The program helps each UTC employee who wants for education to pays their college tuition‚ books‚ fees and even time off to study. David also extended benefits for four years to laid-off workers who had been relocated. He even added another incentive

Is NASCAR a Sport? The National Association for Stock Car Auto Racing (NASCAR) is fairly new to the realm of sports. There is a known debate about whether NASCAR is a sport‚ some people say it is not a sport‚ but I say it is. The definition of a sport is “An activity involving physical exertion and skill in which an individual or team competes against another or others.”(Webster). In a sport the key factors are the physical capabilities and skills the competitor acquires while determining the outcome
