Fire-fighting as we know it today has gone through a long history of development and changes since the first recorded firefighting attempts were created in the 2nd Century in Alexandria (A Fire Pro, n.d.). One example of this would be the modern pumper truck, or pumper apparatus. The first self-propelled steam powered fire engine was built in New York in 1841 and began the chain reaction of developments that created the fire apparatuses that people know and love today (Calfee, n.d.). When the internal combustion engine was created in the early 1900’s, many departments began to turn away from the steam driven apparatuses that were currently in service. There was one flaw with these new machines though, it had to have two engines to operate …show more content…
These trucks include the engine, which is the standard apparatus, the tower, an apparatus with a hydraulic ladder attached that allows for easier maneuverability, and the pumper truck. The pumper truck itself has gone through many changes over the course of the last hundred years motorized apparatuses have been around. In the 1920’s, pumper trucks could only pump between 400- to 600-gallons per minute. These pumpers by the 1940’s, known as Class B pumpers, were replaced by Class A pumpers. These Class A pumpers could pump an average of 500-gallons per minute or more through the 1940’s and 1950’s. By the early 1970’s though, Class A pumpers had a rating of 750-gallons per minute, which increased to 1,000-1,250-gallons per minute in the late 1970’s. By the mid 1990’s, however, is when we get the pressure we operate at today: 1,500-gallons per minute (Fire Apparatus and Emergency Equipment, 2010). But what created such a high pressure? The horsepower of the engine did. In the 1940’s to 1950’s, the engines on the truck only had 110-150 horsepower, which was increased to 160 to 190 horsepower in the 1960’s. In the 1970’s, there was a switch from gasoline to diesel, causing the horse power in a commercial engine to go from 220 horsepower in the early 1970’s, to 210-240 horsepower in the late 1970’s. By the 1980’s, engines were at 240 to 280 horsepower. And finally, the big jump came
The 7.3 Diesels for Sale near Bonney Lake at Puyallup Car and Truck are powered by Ford’s legendary 7.3L Power Stroke® Turbo Diesel engine. This engine revolutionized the trucking industry when it was first produced because it offered outstanding power, an incredibly efficient turbocharger, impressive fuel economy, and low CO2 emissions. The 7.3L Power Stroke® Turbo Diesel engine was even ranked by Diesel Power Magazine as one of the top ten diesel engines ever produced. Rest assured that you would be getting great value for money if you acquire any of the 7.3 Diesels. These trucks will also amaze you with how durable and reliable they are. They can last longer than most of the trucks that were produced after them, and they always offer trouble-free service with low maintenance.
There was always a demand for trucks with the comfort of a passenger car, or a passenger car with the load capacity of a truck. In response to this demand Ford released the Ranchero in 1957. To compete with Ford’s Ranchero, Chevrolet created the El Camino whose first release occurred in 1959. Over the years, Chevy has made several modifications to the El Camino to improve performance and style. Since Chevy stopped producing the El Camino in 1987, it has become a collectible classic. This essay will focus on several of the engine and body modifications that were made between 1957 and 1987.
...hed “piggy-back” service. The first mechanically refrigerated van was introduced. In 1925, there were 500,000 miles of hard surface roads in the U.S. In 1926, a fully loaded 2 ton truck was driven from New York to San Francisco in five days.
Over the next few years however, Chevy's continuous remodeling, unlike Ford's, caused Chevy to take first place. By 1925, Chevy was offering multiple trucks and cars. Introduced the six-cylinder in 1929. In 1929 but mainly in the Thirties The Great Depression became more difficult, Chevy's slogan: "The Great American Value" stilled helped them manage to sell an ample amount of vehicles. Chevy's were known for both style and class thanks to designer Harley Earl, who gave Chevy cars, like the 1932 Deluxe Roadster, the look of the luxurious Cadillac brand. Also he incorporated the first 'Knee-Action front suspension in low price category. In 1935, the Chevy Suburban was introduced. It was the first continuously produced line of truck based 'wagons', now known as SUVs. Chevy's style had similar characteristics to that of Cadillac, although Chevy's were priced much lower, like the Sports Roadster, priced around $445 during the Depression years. Over the past 81 years, the Chevy Suburban has become that longest continually produced vehicle 'nameplate' in the U.S., still having many of the same purposes now in 2016, as it did in 1935. Chevrolet entered the Forties with a bright outlook and new models of cars, then World War 2 started. Chevy had massive war efforts and helped the Allied forces. After WWII, people couldn't wait to get new cars & trucks, with newer
Fires were a very common obstacle at the time, but nothing was even close to the fire of 1871. On October 8th, firefighters received a call from the neighbor of Catherine O’Leary. Neighbors reported seeing a number of flames coming from the cow barn. Firemen instantly spotted the fire, but miscalculated how big it really was. This event was historically known as the Chicago Fire of 1871 (“People 7 Events”).

'Is it true that long ago firemen put fires out instead of going to start them?’ ‘No. Houses. have always been fireproof, take my word for it.’ ‘Strange. I heard once that a long time ago houses used to burn by accident and they needed firemen to stop the flames.’ He laughed.
Imposing even when not in motion, monster trucks of today are high-octane mechanisms of mayhem. The evolution of these arena-filling creations garners great interest within the auto culture, given the capacity for performance today’s formidable monster trucks possess. Modified trucks emerged as sideshow entertainment, but today the industry’s grandest machines fill some of the nation’s most sizable venues with their gravity-defying feats, as families marvel at the bedlam on display when truck capabilities are put to the test.
In 1960, the American car landscape itself had expanded as Detroit began offering “compacts” alongside their full-size models. Many drivers, however, were looking for something in between these full size and compact model; this interest gave way to a new class, the intermediate. With many innovations between 1960 and 1964, like the 406 cubic inch V8 from Ford, the 389 from General Motors, and the wedge V8s from Chrysler, the golden age of muscle cars began in 1964. The Pontiac Tempest G...
Electric traction had numerous advantages over steam railroads. One major advantage was electric locomotive’s ability to pull heavier loads than steam locomotives (Bezilla, 30-31). One statement from electrical manufacturers’ stated that an electric locomotive could pull from five times its own weight on a 2% grade, whereas a steam locomotive on the same grade could only pull two times its own weight (Bezilla, 31). In addition to this, the electric motors could sustain higher currents for a short time in order to increase horsepower dramatically; steam engines had no analogous feature (Bezilla, 31). These factors combined allowed for electric locomotives to accelerate more rapidly, even while pulling more weight, than steam locomotives (Bezilla, 31). The electric motor also had less moving parts and thus needed less maintenance than complex steam engines (Bezilla, 31). For example, the Pennsylvania Railroad’s electric locomotives in 1940 were typically running 90% of the time, but the steam locomotives that the electric ones replaced had only ran 69% of the time (Bezilla, 32). The...
In the 1920s, the automobile industry was being quickly innovated by companies coming out with new cars, very quickly. In 1901 the new Detroit factory burned down and the only automobile to be rescued from the flames was a gasoline powered runabout, the “curved dash” Oldsmobile. Also in 1901, there was a discovery of a seemingly “inexhaustible” supply of oil near Beaumont, Texas. These rich deposits of petroleum made gasoline readily available and gave added impetus to the internal combustion engine in its competition with steam and electric power. In March, fires destroyed most of the Olds Plant and the only car that was saved was the Curved Dash olds. Olds rebuilt immediately and put all the production resources into the little Curved Dash Olds, the “Merry Oldsmobile”. A car was envisioned which weighed 500 pounds and could be sold for $500. Actually, when the famous Curved-Dash Oldsmobile runabout car was finished, it weighed 700 pounds and was sold for $650. Between 1901 and 1904, over 12,000 Oldsmobile cars were built and sold. This was the first volume production car in the world. Speedometers appear first on Oldsmobile. To serve as an advertisement, a Curved Dash Olds was driven from Detroit to New York. This was the longest automobile trip that had been made in the U.S. until that time. Later, in about 1923, standard equipment included four wheel brakes, foot-controlled headlamp dimmer switches, and power operated windshield wipers. On Feb. 2, "Ethyl" gas was first put on the market. The lowest priced T was the runabout, selling at $265. 1908 October 1, Henry Ford put the first of his T's on the road. The 4-cylinder, 20-horsepower T was available in two styles. The runabout sold for $825, the touring for $850. During the last three months of 1908, the Ford Motor Company sold 6,000 cars. William C. Durant sold 9,000 Buick’s during 1908. The Ford Motor Company greatly outpaced its competitors in reconciling state-of-the-art design with moderate price. Cycle and Automobile Trade Journal called the four-cylinder, fifteen-horsepower, $600 Ford N (1906-1907) "the very first instance of a low-cost motorcar driven by a gas engine having cylinders enough to give the shaft a turning impulse in each shaft turn which was well built and offered in large numbers." Deluged with orders, Ford installed improved production equipment and after 1906 was able to make deliveries of a hundred cars a day.
In 1889, the configuration of the “V” engine was introduced. The reason it is called the V engine is because; the engine as a whole gave the appearance of the letter V when viewing it from the crankshaft. Originally this engine was made with just two cylinders. For a long time the engine only had one crankshaft and one crankpin. After reviewing the engine, engineers decided to incorporate two crankshafts and two crankpins. This gave each crankshaft less mass. With both crankshafts having less mass and carrying less inertia it allowed them to move quicker. Since the crankshafts moved faster the engine could rev up and down faster.

Technology was at the top of its game during this time. We had new inventions like the automobile, flights, and mass broadcasting.The automobile before was seen or known as a luxury items and only those who could afford them owned them, but by the 1920’s vehicles were being mass-produced and were commonly seen. Alfred Sloan who was the president of general motors created began devoting more time to automotive styling. His technical advances of the decade included four wheel brakes, automatic engine temperature control, schock absorbers, automatic choking, and adjustable rides; all of which improved the ride and comfort of the car (Rose,216).
