one of the highest evaluated classes in the University ofColorado’s School of Engineering. Students clearly enjoy the class, the process of learning todesign a spacecraft, and the feeling of accomplishment – despite the significant workload -- bycompleting the class. For some students the work in this class has been discussed at jobinterviews and has become the basis for a job offer. Two aspects of the class receive criticismeach year: a) the in-class presentations and b) the book. A small percentage of the class,particularly those who do a good job with public speaking, view the in-class presentations as awaste of time. Most students, however, show marked improvement in speaking capability bygoing through this process.Classroom Management

Figure 4, 5 and 6. Forexample, these angles are calculated as follows:2 a. If both longitudes are east or both are west of the prime meridian through Greenwich, England, then use (LOI – LOL) or (LOL – LOI) whichever is positive. b. If the longitudes are on opposite sides of prime meridian, use (LOI + LOL) or 360° - (LOI + LOL) whichever is less than 180°. c. Repeat a. and b above to calculate angles (LOI-LOO) and (LOL – LOO).Spherical triangle side NF is shown in Figure 4. NF is calculated as follows:2 Cos (NF) = ((Cos (PI) Cos (PL))+ (Sin (PI) Sin (PL) Cos (A))) (7) NF = Acos ((Cos (PI) Cos (PL))+ (Sin (PI) Sin (PL) Cos (A))) (8)Where, A = Central angle (LOI

some students have very good grasp of these principles,majority of the class have trouble in application of these concepts. The computation oftransfer functions in analytical form requires the knowledge of partial fractions andLaplace Transforms. Manual computation of transfer functions is rather laborious foreven some simple systems. MATLAB software can be easily used for this purpose and itis efficient in applying Laplace Transform in order to find the transfer function.Rules for Modeling 1. Degrees of Freedom: (a) Every degree of freedom [Xi] is associated with a mass [Mi]; (b) A degree of freedom without a real mass is associated with a virtual mass of zero magnitude (or zero-mass). 2. Stiffness Matrix: (a) Diagonal elements

A set of engineering drawings was prepared in the draftingworkbench (Appendix B), and the DXF file was imported in SurfCam software, which ran theCNC vertical mill to fabricate the form blocks. The CATIA drawing was downloaded on diskand imported in the SurfCam program, and the students needed to write a simple CNC millingprogram to operate the CNC mill.

professor, it was painfully obvious to me that students lackedfree hand drawing skills and that these skills are needed for improving theirvisualization and spatial orientation. Approximately ten years ago, I was tired ofhearing “we can’t do this” from my students, and I figured the primary reason thatthey lacked these skills was simply that no one had ever shown them basicdrawing procedures. Since then, I have attempted to do this and have seendramatic results that followed when sketching is taught just fifteen minutes or soweekly during the course of a semester. Initially, the goal of this effort was simplyto provide students with a skill to help them understand their ideas and presentthem to others
