electric circuitclass and associated lab. Students are then instructed on how to build a LabVIEW™ program toread and convert the rotation rate to a linear velocity as well as a volumetric flow rate.This method of integrating theory from different engineering theory courses by engagingstudents in practical applications helps the students to further their knowledge and understandingin both targeted areas. We are working on new experiences to integrate additional topics.IntroductionTo be an effective engineer and apply the fundamental principles of mechanics, materials,circuits, fluids, thermodynamics, etc. it is necessary to understand how these different distincttopics inter-relate. The skill of knowledge transfer is particularly difficult for

 Mechanical DesignThe centerpiece of the new Intro to ME curriculum is a 9 week lab sequence in which studentsbuild a small bore pneumatic powered potato gun that is controlled using an Arduinomicrocontroller. In the initial 3 weeks of the course, students learn to use the machine shop tofabricate the potato gun components. In the next four weeks, students are introduced to theArduino microcontroller and use it to control a solenoid piloted pneumatic valve, (used to fire thegun), as well as a stepper motor, (used to adjust the angular position of the gun). Finally, in thelast 2 weeks of this project, students integrate the electrical and mechanical components, alongwith a firing control program to operate the gun. While potato cannons are undeniably

addressed in the Resultssection.Figures 4 and 5 from 2008 show a great deal of quantization staircasing and the poor altituderesolution. The third and fifth columns of plots in Figure 6 are the sensor data from theaccelerometers and rate gyros from a 2008 flight. The plot in the third column on the third row isthe built-in accelerometer on the R-DAS. It shows severe quantization noise. The otheraccelerometer and rate gyro plots show much less stairstepping due to careful attention to scalingthe signals for the 10-bit ADC. The other plots on Figure 6 are axial position, velocity, androtation angle calculated by numerically integrating the data. While the curves are smoother, theoffset integration errors are unacceptably large. The flight reached an

resolution. Once an error was integrated into thesystem, it is tedious to find and correct. This is amplified because Patran doesn’t allow for thereversal of more than one step. It would be preferred if a step-by-step manual was developed togive the best way to approach the bridge model.”“The most difficult part of the class project was the entire model. Due to its complexity and sizethere were a large number of nodes. Trying to determine the exact nodes to RBE2 to one anotherwas very difficult.” 3) Comment on the quality of the laboratory manual and class instruction, and make suggestions for improvement.“The lab manual needs to be in color, with revisions in grammar of the content and updatedphotos for instructional purposes. ““My

, especially those associated with the instructors’ personal research/consulting experience, received highly positive feedback and students would often approach the instructor to ask follow up questions. These types of case-studies should be more fully integrated throughout the semester, rather than concentrated at the end as they were in the Fall 2015 semester.  Students enjoyed the creativity associated with the final design project and the fact that each team’s problem statement was unique. Many requested that some of the experiment- based activities from earlier in the semester be replaced with small design challenges. Instructors would have to be selective to insure curriculum topics are still addressed if this

samescenario tested in this experiment. Figure 20 shows the results of the FEA simulation run for theFSAE spaceframe. The simulation was run with 400 ft-lbf, an average suspension load, appliedacross the front axle. The torsional stiffness at the front axle from FEA was calculated to bearound 1100 ft-lbf/deg. This is within 10% of the value calculated from the experimental setup.

power control or fan speed control is required. Students in an instrumentation or controlscourse could use the USB interface to the Arduino to collect data and/or reprogram the Arduino toperform feedback control.Six of the devices with varying sized heat sinks were used in a trial homework assignment in anundergraduate heat transfer course with 75 students in Spring 2015 and in another section of thesame course with 57 students in Winter 2016. At this point, we have no quantitative assessmentdata.OverviewThough laboratory exercises are a standard part of an engineering curriculum, there are a widevariety of ways that labs can be implemented. In recent years a number of simple experimentshave been developed that help to make laboratory
