Mini-Lab Projects in the Undergraduate Classical Controls Course Jeffrey S. Dalton, Daniel S. Stutts, and Robert L. Montgomery University of Missouri-Rolla Rolla, MO 65409 Abstract: To address a common complaint from students that the undergraduate controls lecture course in mechanical engineering is too abstract, an electromechanical mini-lab was developed. The term “mini-lab” is used here to emphasize the fact that the lab augments the lecture, but does not replace a full controls lab. This mini-lab consists of a simple DC motor and flywheel with either tachometer speed, or potentiometer

in the 1940’s is a goodexample of the drudgery and tediousness of extended pre-computer calculations. The digitalcomputer fundamentally altered the use of “manual” calculations and replaced it with machine-based computations. Initial efforts were hard-wired (literally) with patch boards, but by the early1950’s higher-level programming languages evolved. For engineering computations,FORTRAN became the dominant programming language. However, as these advances weretaking place, both the engineering workplace and engineering education struggled to effectivelyutilize the promise of the “computer” and to define the relationship between the computer andengineering. Indeed, one could argue that these struggles are ongoing.The situation is much

The GAO has reported that soil losses from poorerosion control are 25% worse than soil loss conditions in 1934 during the "Dust Bowl” days.This loss of soil cover is a huge problem in itself and what it carries with it compounds theproblem even more.

The differential operator can be manipulated alge-braically, and in many ways is analogous to the Laplacian ‘s’. This can be seen in texts [2][3] thatuse the differential operator. An example is shown in Appendix A. The block diagram shows anegative feedback system using a PID controller for error compensation. The ‘D’ is an alternatenotation for the differential operator ‘d/dt’. If the system starts at rest the ‘D’ could be replacedwith the Laplace ‘s’. In this case the system block diagram is simplified, a root-locus analysis isdone, a Bode plot constructed, and the system response is found (a zero

IntroductionFinite element analysis (FEA) gained widespread use in specific industries, most notably theaerospace industry, in the 1960’s and 70’s. A mainframe computer was required to run theprograms, so the use of FEA was generally restricted to larger companies. The role of the stressanalyst was fairly specialized.

The goal was to circle the one correct object that would bemade by folding the flat plate with no overlaps and no concealed sections of the plate foldedinside. The pre-test question was not duplicated in the post-test. This type of test was closest toone of the sections of probably the most widely used spatial visualization tests - Project Talent.Project Talent was a test containing 4 spatial visualization sections that was given to 400,000people in high school in the 1950‘s.
