The Disturbing Role of Television in Accidents and Deaths Involving Children Imagine being a mother or a father standing in the kitchen doing dishes when out of nowhere a familiar scream hits your ears. The first thing you do is ask yourself â€Å"Where are my kids?† The phone rings and your next-door neighbor informs you that he/she has called 911 and you should come right away. You slam down the phone and in a panic you run down your walk across the street, arriving just as the ambulance backs into the drive. Next thing you know your 11-year-old son Billy, broken and bleeding, is being sped to the hospital. Far-fetched, as this story may seem it is happening more and more everyday. Billy got hurt because he and his friends were re-enacting a move they had seen on WWF the night before. Does television really influence good kids to do bad things? The answer is yes depending on the type of program and its content. At a young age children absorb everything they see and hear including things that adults see as minor, or non-influential. Television can do several things, create ideas in a child’s mind, pacify physical energy that could be used productively, tell children that unacceptable behavior is ok, and that humans are invincible. All of these ideas are false and can lead to destructive behavior and circumstances, and in some cases death. â€Å"The statistical correlation between childhood exposure to violence in media and aggressive behavior is about the same as that between smoking and lung cancer† (Atkinson, Michael. 59) (put a period after the parenthetical citation, and only include the author’s last name and page number in parentheses) We all know that for anyone who smokes a great deal lung cancer is almost inevitable, this causes great concern because most children spend much of their spare time in front of the television or playing video games. (make more explicit the connection between the effects of smoking and the effects of watching too much TV) Many childhood accidents related to television are in the form of copycat crimes says Michael Atkinson in his article â€Å"The movies made me do it†, â€Å"Copycat crimes have attained front-burner notoriety, and some day soon Hollywood’s liberty will be pitted against the perceived welfare of American children† (58). Many chil dren’s cartoons such as â€Å"X Men† and â€Å"PokeMon† tend to be very violent and anger oriented, (semicolon) therefore when children copycat what they see often times they end up hurting themselves or someone else, possibly even causing death.

1. What development in motor cars led to the need to replace the block brake? What was the replacement? With the adoption of pneumatic rubber tyres for cars in 1895, the block brake became impractical and was replaced as an automobile brake, and was replaced by the contracting band brake. 2. Who invented the drum brake? In what year did this occur? In 1902 Louis Renault invented the internal expanding drum brake. 3. Why was the drum brake superior to its predecessors? First, the shoes are enclosed on the drum so the friction lining is away from water or dirt, so they last longer. The drum brake also exhibits servo-assistance, in both forward and reverse; the leading shoe exhibits servo assistance in forward travel, the trailing shoe in reverse travel. 4. Why are the disc brakes used extensively now? The disc brake offers better heat dissipation than the drum brake and also offers better weather performance as water is thrown off the disc by centrifugal force. 5. Why is asbestos still allowed in brake linings in Australia? Asbestos gave the break lining greater stability at higher temperatures, thus the linings are more resistant to break failure form the heat. 6. The coefficient of friction (Â µ) is ratio between what two values? The coefficient of friction is the ratio of the frictional force present and the normal reaction to the matting surfaces. Â µ=FFRN 7. What is the tensile stress in a brake cable of diameter 2 mm if the tensile force in the cable is 200N? 8. Draw a stress strain curve for mild steel; label the proportional limit, the upper and lower yield points and the UTS. . What is the difference between elastic and plastic deformation? 10. State Pascals principle. Why is it important to hydraulics? 11. What is steel? 12. What is the difference between austenite and ferrite? 13. What is pearlite? 14. What happens to the hardness of steel as the amount of cementite increases? 15. Describe what martensite is. 16. Why is manganese added to steels? 17. What effect will nickel have if added to a low alloy steel? 18. Why is molybdenum added to the nickel-chromium steels? 19. Why is Hadfield steel used for? What is different about its structure at room temperature as opposed to plain carbon steels? 20. There are three types of stainless steels available. List three and describe the uses of each? 21. Which stainless steel is non-magnetic? 22. What is the difference cast iron and steel? 23. Carbon appears in different forms in cast irons, how does it appear in white cast iron and grey cast iron? 24. Which type of grey cast iron is stronger, fine or course? 25. How do SG cast iron and CG cast iron differ? 26. Blackheart malleable cast iron has free carbon present in Whiteheart malleable cast iron? 27. Is free carbon present in Whiteheart malleable cast iron? 28. Why is copper added to break pads? 29. What type of resin is used to bind the break pad together? 30. Draw two stress strain diagrams, one showing high toughness, and one displaying high strength but a brittle failure. 31. What are the four hardness tests available? 32. Find the tension in the vertical and horizontal cables for the brake system shown. Slove this problem graphically then analytically.

Identifying Organic Compounds Joe Harris 11/12/07 1. Background Organic compounds are, by definition, any chemical compound containing carbon. These compounds include carbohydrates, polysaccharides, lipids, proteins, and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the fats of a cell. Proteins are the building blocks of muscle in a cell. Nucleic acids are used to transfer genetic information from one cell to the other.
