Cars - Essay Example Gasoline has a much higher energy density than batteries do. For example, it takes about 1,000 pounds of batteries to store as much energy as 1 gallon or 7 pounds of gasoline. As fuel tank is the energy storage device for gasoline engine, the batteries in a hybrid car are the energy storage device for the electric motor. Gasoline in the fuel tank can only power the gasoline engine but the electric motor on a hybrid car can put energy into the batteries as well as take energy from them. The role of transmissions on hybrid cars is same as the transmissions on conventional cars. Some hybrids have conventional transmissions, like the Honda Insight. Other hybrids have different ones, like the Toyota Prius. The simplest forms of self-propelled motorized transportation are electric cars. Its driving mechanism or engine is made up of a succession of batteries attached to an on and off switch that in turn is attached to an electrically operated motor. The wheels are driven by the electric motor, which thereby propel the car into motion. Generally the amount of energy is controlled by a complicated technique that goes into the motor and the gear system and further helps the wheels in a more capable manner. Some electric cars also have solar collectors that convert solar energy into electricity for slow recharge of the batteries. Here question arises: why should you bother with an electric car The... Here question arises: why should you bother with an electric car There are several reasons as its answer. Electric cars offer a curious driving experience with exceptional control as well as quick initial acceleration thanks to their low center of gravity. Even at lower speeds, it's almost continuous torque makes it easy to climb curbs, sharp turns and steep inclines. Further, the fuel cost is increasing regularly; therefore, use of electrically charged cars is an ideal choice. A simple electric car can be built in just two weeks. It is so fascinating and easy. Electric cars can even be built by anyone because these cars are very simple in overall structure. The main components are a simple frame, an electric motor, a car battery, basic wheels and an electric on and off switch. Although, the task requires some extra efforts as well but it becomes quite easy especially for those have a simple blue print, knowledge of electric currents and wiring and the parts to assemble them all together. Did You Know How Vehicle Size Classes Are Defined The size class for cars is based on interior passenger and cargo volumes as described below. The size class for trucks is defined by the gross vehicle weight rating (GVWR), which is the weight of the vehicle and its carrying capacity. Fuel economy regulations do not apply to heavy-duty vehicles, so they are not tested. Cars Class Passenger and Cargo Volume (Cu. Ft) Two-Seaters Any (cars designed to seat only two adults) Sedans Mini-compact Subcompact 85 - 99 Compact 100 - 109 Mid-Size 110 - 119 Large 120 or more Station Wagons Small

Emergency Response Effort Directed To a Major Aircraft Mishap Research Paper

Emergency Response Effort Directed To a Major Aircraft Mishap (Aircraft Crash and Emergency Management) - Research Paper Example The Sioux Airport after recognizing the situation informed the entire rescue agencies to reach the place immediately where flight had landed. Following the crash, the rescue members had performed effectively to save the passengers. The fire fighters had performed efficiently to fight the disaster. Despite huge challenges, the emergency plan was operated in an effective manner as the airport emergency facility had already planned to combat if there was any occurrence of disaster. 1.0 Introduction United Airlines Flight 232 had left for Chicago on 19 July of 1989. The three hydraulic systems of the airplane had failed to operate after covering a certain distance. Sudden explosion had occurred which had shook the entire airplane. Finally, it was determined that one of the engines of the flight had failed. Due to the imbalance of such parts of the airplane, disaster occurred (Bibel, 2008). In this study, entire events that had taken place before and after the crash have been discussed. The role of emergency plan and that of the firefighter during the incident of the crash have been included. The problems that were faced by the rescuers during rescue are identified. The processes and the steps have been determined that had been adopted and implemented by emergency plan throughout the rescue process. The role of fighters in extinguishing the fire and the way they rescued the passengers is included. The paper also explains the role of emergency rescue in improving the rescue process of the passengers. 2.0 Events Leading To Before and After  Wreck United Airlines Flight 232 had no problem in its ‘tail mounted engine’. It was checked properly one year before the crash. However, on 19 July, 1989, a sudden problem raised in that part of the airplane causing catastrophic failure due to prolonged exhaustion pressure. A sound of crash was heard from the mounted en gine of aircraft’s tail. At that time, a failure had occurred in the engine fan assembly which had broken the fan blades into sharp pieces and sent the parts of the engine by means of right horizontal stabilizer. Crew at that moment identified that the hydraulic system that controls the aircraft was out of control. The captain tried to land the flight immediately at the nearest airport named as Sioux City Gateway Airport (Conroy, 2005). The first as well as second hydraulic systems were split with the first outburst of engine. The gashes of the hydraulic lines as well as missing parts of the systems lost pressure and hydraulic fluid entered in the entire systems. After the explosion had taken place the hydraulic fluid had totally drained out (NASA, 2008). In-flight emergency, after receiving information about the flight, sent five ARFF (Aircraft Rescue and Fire Fighting) vehicles. The vehicles determined that the aircraft could not reach the airport and might crash. It was re cognized that aircraft might land on runway 31 and as a result ARFF vehicles took their positions in
