GEARBOX DESIGN PROJECT DESCRIPTION You are the designer and you have been asked to design a speed reducer that will take power from the shaft of an electric motor rotating at 1500 rpm and deliver it to a machine that is to operate at approximately 750 rpm. Assume that you have decided to use spur gears to transmit the power and you are proposing to use a single-reduction speed reducer. The power to be transmitted by the shaft is 20 KW and the input shaft is coupled to the motor shaft

Increasing reading speed is a process of controlling fine motor movementperiod. This post is a condensed overview of principles I taught to undergraduates at Princeton University in 1998 at a seminar called the PX Project. The below was written several years ago‚ so its worded like Ivy-Leaguer pompous-ass prose‚ but the results are substantial. In fact‚ while on an airplane in China two weeks ago‚ I helped HYPERLINK http//www.dirtsalad.com/ t _blank Glenn McElhose increase his reading speed 34 in less than

Imagine driving on I-75 as cars race by you at a blink of an eye. You are driving 60 miles per hour‚ the speed limit; they must be doing 100 miles per hour or more. This is not an illusion; this is the reality of driving on a highway. Believe it‚ it happens everyday. Cars race down the road at uncontrollable speeds that cause tickets‚ accidents‚ and sadly death. Speed limits are a must for traffic control‚ for safety in neighborhoods and for avoidance of collisions. Traffic control establishes

Land Speed Record The land speed record (or absolute land speed record) is the highest speed achieved by a wheeled vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used‚ officiated by regional or national organizations under the auspices of the Fédération Internationale de l ’Automobile. The record is standardized as the speed over a course of fixed length‚ averaged over two runs (commonly called

Dispersion and the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming
