An Automobile, Autocar, Motor Car Or Car Is a Wheeledmotor Vehicle Used for Transporting Passengers, Which Also Carries Its Own Engine Or Motor
An automobile, autocar, motor car or car is a wheeledmotor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.[3] Propulsion is a means of creating force leading to movement. Look up propulsion in Wiktionary, the free dictionary. A propulsion system has a source of mechanical power (some type of engine or motor, muscles), and some means of using this power to generate force, such as wheel and axles, propellers, apropulsive nozzle, wings, fins or legs. Other components such as clutches,gearboxes and so forth may be needed to connect the power source to the force generating component. Ground propulsion is any mechanism for propellingsolid bodies along the ground, usually for the purposes oftransportation. The propulsion system often consists of a combination of an engine or motor, a gearbox Automotive engineering is an applied science that includes elements of Mechanical engineering, Electrical engineering, Electronic Engineering, Software Engineeringand Safety engineering as applied to the design, manufacture and operation of automobiles, buses and trucks and their respective engineering subsystems.and wheel and axles in standard applications. n automobiles, the wheelbase is the horizontal distance between the center of the front wheel and the center of the rear wheel. At equilibrium, the total torque of the forces acting on the car is zero, and thus the wheelbase is related to the force on each pair of tires by the following formula: where is the force on the front tires, is the force on the rear tires, is the wheelbase, is the distance from the center of gravity (CG) to the rear wheels, is the distance from the center of gravity to the front wheels ( + = ), is the mass of the car, and is the gravity constant.
