. Statistical tests were conducted and results were documented on the power of simulation.Development of Finite Element AnalysisA computer program was developed by idealizing the flexible pavement into a finite element continuum.In this investigation a layered pavement system was idealized as an axisymmetric solid with finiteboundaries in both radial and axial directions, as shown in Fig 1. The axisymmetric body was thendivided into a set of ring elements, rectangular in section and connected along their nodal circles. Thefinite elements are actually complete rings in the circumferential direction, and the nodal points at whichthey are connected are circular lines in plan view. Because of axisymmetry, the three-dimensionalproblem reduces to a two

. 1Open Ended Problem DescriptionA beam has been chosen as the group problem in the Strength of Materials Course5 because it has anopen-ended solution space such that there is no single solution that will fulfill all the requirements;therefore, it can be considered an ill structured problem. Two objectives are defined for this project: 1. To design and construct a maximum strength beam out of wood board to span ~30 inches and carry a concentrated load at mid-span. The beam must not exceed 8 inches in height. 2. To test the constructed beam, record its response and prepare a report describing the structural response and failure characteristics of the beam.The class was divided into groups with a maximum of three members.

Some studies have shown improved motor performance and increased aerobicendurance with the use of music during exercise [5]. Music has been shown to reduce bloodpressure in performing potentially stressful tasks. A study measured the blood pressures ofsurgeons performing mental tasks. The blood pressures were reduced the most when they wereable to listen to music of their choice while performing the specified task [4].Computer science is no stranger to music.

Since we desired apredictor that was readily available, we decided to use the simpler, easily obtained, cumulativeGPA.In addition to choosing the predictive characteristic of their GPA, we desired the most accurateprediction model. In other words, we set out to determine if simply converting GPA to apercentage was as accurate as other models that considered the distribution of grades. In order toinvestigate this question, we compared the accuracy of three models: • Model 1 – “GPA to Percent”. In this model, we converted each individual’s GPA at the close of the previous semester to a percentage and used this

All of thestudents describe themselves as visual learners and agree that animations, in some form, will beregularly used in engineering classes in the near future. Most students think that their overallunderstanding of particle kinematics and kinetics was significantly improved by using theprogram. They consider the software easy to use and recommended it to instructors who teachintroductory Dynamics classes.In this paper, the software functionality will be detailed.

applications of feedback control techniques.1. IntroductionThe ball-on-beam balance system is a classic example of feedback control systems. The problem is tomaintain the position of a ball at the center of a beam on which the ball rolls along freely. The ball willreturn to the center position after it has been displaced from this location. This system is an effectiveeducational tool for teaching feedback control principles. Some of these systems are commerciallyavailable[1,2,3].The set-up of our ball-on-beam system is shown in Fig. 1. The beam is a 55” long, grooved aluminumbeam that a regular rubber ball can roll along freely. The beam is mounted at the center to a servo motor,which can tilt the beam in clockwise and counter-clockwise directions

Through simple qualitative discussion and demonstration the students were introduced to the fact thatfor every object, regardless of its shape and size, when freely suspended from any point on the shape, aplumb line will always pass through the center of mass. Using two points not on the same line of “masssymmetry” will result in an intersection which is the mass center of the object as illustrated in Figure-2.During this experiment the principal of gravity and how it works was explained and

The stand would need to fit bikes with tire diameters ranging from 20” to 26”, andalso with varying rear axle widths. The design also had to allow for adjustment of the tension in the drivebelt, so it was decided that the grain crusher’s location would be adjustable to provide such tension. Theonly fixed components would be the center drive axle and its supports. An overview of the previousdesign is shown below in Figure 1 (Bonzella et al., 2006).
