Answer KeyPart 11. There are over 14,000 thousand parts in a modern automobile.2. The heart of the car is the engine.3. While you are driving thousands of miniature explosions per minute are blasting away in the cylinders.4. In 1878 Nickolas Auto of Germany built a single cylinder power plant that was smaller and stronger than others around the world.5. The Duria brothers built one of the earliest successful gas powered vehicles in the U.S. in 1895.6. 1908 was the year Henry Ford introduced his Model T.7. In 1950 Henry Leland’s Cadillac Company became the first manufacturer to mass produce eight cylinder engines arranged in a V shape.8. John Dillinger once wrote a letter to Henry Ford that stated, “When I’m stealing a car I always look for a Ford…”9. Things would get a lot tougher in the next 50 years as consumers demanded more power and the government laid down the law on pollution.10. The end of World War II was in 1945.11. As oil and gas prices continued to rise in the late 1960’s and 70’s, 4 and 6 cylinder engines began to make a comeback.12. Emission’s standards grew more strict in the 1970’s, the industry turned to the Catalytic Converter.13. Other recently introduced models are trying to have the best of both worlds by using two sources of power, these are know as Hybrid vehicles.14. The exterior of a modern automobile is a combination of plastic and hardened steel.15. One of the earliest completely enclosed cars was the 1905 Cadillac Osceola.16. Clay gave Earl the freedom to test many different shapes and ideas, it is an innovation that’s still in use today. 17. Fiberglass made the Corvette light and allowed for stylish curves.18. Safety standards from the government started to prohibit any sharp corners on car bodies.Part 2 --Start at 30 MINUTES19. Early cars didn’t have unitized bodies just metal ladder shaped structures known as chassis.20. Tires are made of a couple of layers or plies.21. By 1910, treads gave early drivers better grip.22. Even today, natural rubber remains an important ingredient.23. The French Michelin Company invented the radial tire in 1946. 24. Radials were better, but car makers in Detroit always put price above performance.25. Goodyear’s run flat tire can be driven for 50 miles without any air pressure inside.26. The most forceful part of the car is the brakes.27. Disc brakes first appeared in Europe in 1945.28. Combining disc brakes with electronic sensors and controls led to Anti-Lock brakes.29. Even with cushy air filled tires and a strong frame you’d still have a pretty rough ride without a suspension system.30. A coil spring and a shock absorber into one unit, it became known as the McPherson strut suspension system.31. Modern shock absorbers can adjust themselves up to 10 times a second during driving.32. One of the most important parts of the automatic transmission is the Torque converter.33. Driving became a lot easier in 1939 when Oldsmobile introduced its Hydro-Matic transmission.34. Since you didn’t have to use a clutch or shift gears, the ease and simplicity of automatic transmissions helped open the car market to more people than almost any other automotive invention. Part 3 --Start at 58 MINUTES35. Before the turn of the century cars didn’t even have steering wheels, drivers used simple sticks known as tillers.36. A few cars in the early 1900’s began experimenting with rack and pinion steering.37. The electric power steering system will basically replace the hydraulic power steering systems because it’s more efficient.38. The alternator is a little powerhouse that sends current to all the electrical components throughout the car, it even recharges the battery.39. In the first few decades of driving, motorists had to use a hand crank to start the engine.40. The term “cranky” comes from having a bad day crank starting your automobile.41. Henry Leland quickly installed electric starters on all 1912 Cadillac’s. 42. In the mid 1950’s, manufacturers switched from 6 Volts batteries to 12 Volts.43. A car in the 1950’s may have had 50 circuits, today there is about 1800 of them.44. Researchers are now exploring the possibility of boosting the car battery from 12 Volts to 42 Volts.45. Keys were not used to unlock the steering column and start the car until Chrysler introduced this in 1949.46. Heating and Air Conditioning are two of the most basic creature comforts.47. Nash’s system became the model for all other heaters.48. A layer of plastic inside the glass keeps it from breaking into big dangerous pieces.49. Seatbelts actually occurred as early as 1903. 50. In 1960 drivers had to move the windshield wipers back and forth by hand.51. Air bags were combined with seatbelts to provide even greater safety in the 1970’s.52. Air bags reemerged in the 1987 due to government mandates.53. Computers are the key to most of the smarter, safer, faster systems on today’s cars.54. The invention of the microprocessor was in 1971.55. Well, we definitely got our hands dirty today which is always a good thing! ................
