andPractice in 1991 1: There’s an old Bob Newhart routine about baseball. In it, an adult game manufacturer is talking on the phone to Abner Doubleday who is explaining the rules of his new game, baseball. Doubleday explains, "Three strikes and you’re out, four balls `." "Why four balls?" asks the manufacturer. Why, indeed? The engineering curriculum, leading to a Bachelor of Science degree, has been a four-year program at most institutions for as long as they have offered degrees. Programs that required longer eventually found it difficult to compete for students. In the 1950’s and early 1960’s, most five year programs in existence were being phased out as the engineering programs, in

Basically,a ratio of output to input is computed to form an estimate of the FRF and then modal parametersare extracted from the measurement.This graphic is always good to have handy to keep everything in perspective when coveringdetailed areas of the theory of experimental modal analysis.

EngineeringAppropriate Engineering is a holistic approach to engineering design that incorporates social,political, cultural, environmental, economic and human empowerment issues as central, alongwith technical considerations, to the process. For example, many rural inhabitants in much ofAfrica have low incomes and cannot afford to buy batteries for their portable radios. However,hand-cranked radios, which use a mainspring to drive a little dynamo, are highly functional anddesired because of their low cost. These radios allow a small village to “zip back into theInformation Age with a twist of the wrist.”9Many Appropriate Engineering principles have evolved from the work of British economist E. F.Schumacher in the late 1960's and early 1970's on what he called

According to McDonald, “rather than admit to such unladylike leanings, it was notunusual for women in the 1800’s to claim to be under the influence of spirits when defendingtheir inventions.” 9 For example, Amanda Theodosia Jones told the world that her idea forvacuum canning came from her brother’s ghost that was instructing her from the grave, and notfrom any personal cleverness9. The ironic part of all of this is that being mechanically talentedwas not accepted, but receiving instructions from a ghost was.This paper focuses on women who are currently in the fields of

The question arises how to deal with the discrepancy. Does it exist only in ahydraulic valve, or in other flow cases, too? With a better understanding of how the reactionforces are created, it would be easier to make better designs.Bibliography1. Guillon, M. Hydraulic Servo Systems - Analysis and Design.
