The greatest effort is required from a locomotive when starting. At this time, if the engineer applies too much power to the wheels (i.e., for a steam locomotive, the engineer opens the regulator too far) the turning force applied to the wheel will greatly exceed the opposing friction force affected by the surface of the rail, and the wheel will turn without being able to move the train forward.
The vertically mounted paddle wheel, at side or at the stern, was the first propulsion scheme used with steam power, but naval authorities were concerned about the vulnerability of the wheels to damage, whether in combat or peacetime use, and sought to increase the efficiency of ship designs, as the navies of the world began to switch from wooden hulls to iron ones.
It is transferred to the track by the driving wheels [2] of many steam locomotives. It is an out-of-balance force on the wheel (known as overbalance [3]). It is the result of a compromise when a locomotive's wheels are unbalanced to off-set horizontal reciprocating masses, such as connecting rods and pistons, to improve the ride. The hammer ...
Wheel flats on railway vehicles are very evident by a distinct “bang-bang” noise made in time with the speed of the train. It is normally necessary to use a wheel lathe to remove a layer of wheel tread caused by a severe flat spot or cavity, which reduces the operational service life of the wheel and is a major operating cost to the rail ...
A burnout (also known as a peel out, power brake, or brakestand) is the practice of keeping a vehicle stationary and spinning its wheels, the resultant friction causing the tires to heat up and smoke. While the burnout gained widespread popularity in California, it was first created by Buddy Houston, his brother Melson and David Tatum II at Ted ...

The sounds of sobbing, prayers and anguish echoed through the departures hall of an airport in southwestern South Korea on Monday as families of the victims killed when a passenger jet crash ...
Besides the flux capacitor, the time circuits, and the Mr. Fusion chamber, the DeLorean had numerous other equipment that aid its ability to function: a keypad used to type in a target date, a lever that activates the time circuits, a pair of vents on the back that heat the vehicle after it travels through time, a plutonium chamber that serves ...
