Theyalso can choose among project ideas proposed by the instructor. In either case, students arerequired to clearly state their project title, objective(s), and the significance of the project toindustry, science, technology, health, etc. Upon approval, the projects start a three-phase processwith due dates specified in the project guidelines given to the students. All groups need tocomplete approximately the same tasks.In Phase One, they have to determine the sensing device required to transduce the desiredmeasured quantity to an electrical signal, determine a complete data acquisition

, students were guided toward designing load cell transducers configured ascircular aluminum rings because aluminum rings of various sizes were readily and inexpensivelyavailable from the department machine shop. Some student teams whose members had machineshop experience chose to design and fabricate transducers of other types, such as a C-shapedtransducer which had multiple attachment points to allow its range to be adjusted and an S-shaped transducer which was similar to some commercial designs.The load cell transducers designed by the students must transform externally applied forces intoa measurable voltage. Such transducers consist of a structural frame with several strain gaugesattached. In a common embodiment, shown in Figure 1 below, the

If during the final test the team encountered a problem and wanted to request a re-test,this was allowed, but their final performance grade dropped 7% each time. Of the 16 teams thatfaced this performance grading, 14 successfully raised their quarter above 6 feet, one team raisedit two feet, and one team’s design did not function.Case 2 - The main difference in Case 2’s final demonstration was that every team competed atthe same time.

To create an opportunity for collaborative research and design efforts between theundergraduate engineering student(s) and the faculty.3. To design, produce, test, and optimize a cost-effective, reproducible apparatus withoutstanding features.4.

This packet is sent in the format: obj1value + obj2value + Sp byte + verify byte +0x0d. The Verify Byte is a result of byte calculation of the bytes before the Verify Byte. In thiscase, these bytes consist of obj1value, obj2value and Sp byte. In order to calculate the value ofthe Verify Byte, the sum of the previous bytes is found. Then, the 2’s Complement Rule isapplied to the sum of the bytes which is then passed through a modulus of 128. The formulacalculates the correct value for the Verify Byte which is used by the MP2000
