approximately 1 ms after the input changes. This observation matches the predictedvalue.Transitioning to the Frequency DomainStudents were assigned a similar laboratory experiment in the previous circuits class, but thetime-domain experience and time constant measurement were at the end of the assignment. Thisassignment continues on a path to introduce frequency domain behavior.The next part of the assignment asks the students to increase the frequency of the applied squarewave until the square wave period is approximately ten times the circuit time constant. This tasksets the square wave period to 10 ms, and they must determine the frequency to be 100 Hz. Thisexercise confirms that the exponential response of the circuit is independent of the
. For each half bridge circuit, the students again take measurements ofthree different weights. This process is repeated once more for a full bridge circuit using all fourstrain gauges.The final part of the lab requires the students to choose one of the bridge setups (quarter, half, orfull) to measure an unknown weight. At least four known calibration weights are used to create acalibration curve relating weight and strain as measured by their chosen Wheatstone bridgesetup. They then choose some object that they want to weigh, which can be a textbook, abackpack, or even a fellow classmate. This object is weighed on their ‘scale’ – the instrumentedaluminum beam – and then weighed on a calibrated laboratory scale to get the reference value.This

Thus, the reactor facility represents a perfect scale model of a modernindustrial plant with many of the same components and energy transport processes that can befound in any plant. This facility is rather unique within the educational community and it has thepotential to provide a wide variety of educational opportunities and real-life learning experiencesthat are not readily available at most institutions.This paper first describes the physical plant layout and main system components and discussesthe overall web-accessible reactor laboratory system that has evolved over the last few years.

Furthermore,the experiment gave all the students a better understanding of how to operate both a wind tunneland a multi-manometer. Many students stressed that the visual aspect of the multi-manometerwas aesthetically pleasing and gave them a greater interest in the subject matter. Overall, thestudents were grateful for the opportunity to gain hands-on experience and compare real-worlddata to their computer-simulated data. As a result of this project, many university students willbenefit from new, exciting laboratory experiences.ConclusionThis paper has shown a research project where the students designed, manufactured, and testedan airfoil section and a multi

Mechanical Engineering Technologyprogram at CWU each course has a lab section attached and the labs are performed more or lessconcurrently with the related discussion in the lecture. In developing the revisions to the labactivities efforts have been made to make the activities relevant to situations that students couldenvision encountering in various work situations. Lab revisions have been made with an eye onthe fundamental objectives of engineering instructional laboratories, as described by Feisel andRosa (3). The seven labs presented in the current suite of labs are based on a 10 week quarter,with extra weeks given for a self-designed lab. For a semester based schedule there would bemore opportunity to include additional labs such as a
therapeutics, thus PNIPAAm has beenextensively investigated for applications such as protein delivery 58-61. We produce PNIPAAm polymers in our laboratory regularly, and it can be achieved with astraightforward free-radical polymerization of NIPAAm monomer in water using a redoxinitiator 26. The hydrogel can be made magnetic by suspending magnetic Fe3O4 powder inaqueous solutions of PNIPAAm, below the LCST. Upon application of a magnetic field with asolenoid, the presence of the magnetic particles will cause the solution to heat above the LCST,causing collapse of the polymer around the magnetic particles and the squeezing out of the drug.A pulsatile release profile can be generated by turning on and off the magnetic field 53.

We found that it was useful to include an image which shows the correct starting position for the syringe tip before conducing the lab (Figure 9). Figure 9: Image of the tip. The “meat” of the lab is to create a sessile drop on the surface. It is imperative to note that the contact angle measurement technique samples approximately 3-20 Å of the surface and so students should wear gloves and keep your specimens clean as the oils, dirt, etc, from your fingers will affect measurements. Note too that static electricity can adversely affect results. We found that dispensing 0.25 µl drop

Thisexperimental system has been developed for an undergraduate laboratory in thermodynamics forMechanical/Chemical Engineering students.IntroductionThe heat of combustion1 of a fuel is the amount of heat generated by the complete combustionof a unit weight of fuel and it is expressed in Joules/kg (or other similar units such as BTU/Ib orcalories/gram). It is experimentally determined by combustion of an accurately weighed sampleof fuel in a calorimeter and measurement of the heat released. In this experimental system, anOxygen Bomb Calorimeter2 has been used. The temperature rise, T, resulting from the heatreleased
reduction factors used in design standards account for most of these errors. The exception is idealizing a structure that behaves between two extremes (e.g., semi-rigid connections, semi-flexible diaphragms). These exceptions, however, can be addressed by performing analysis on the two extremes and designing based on the most severe conditions. 2. Assumptions inherent to the analysis method or design equations. Every analysis method and design equation incorporates some assumptions. An example is the expression for shear capacity of a reinforced concrete beam without stirrups; that equation is an empirical lower bound based on laboratory tests. The load and strength reduction factors used in design standards account for these

A small group of upperyear students volunteered to complete the Concept Inventory. Students currently in their fourthyear of engineering would not have completed this particular laboratory experiment; rather theywould have learned the concept of crystal structures with 2D materials from lecture slides andtextbooks, etc. Those in third and second year engineering would have completed thisexperiment. The research group plans to continue delivering the MCI to these students annuallyto gather whether completing this lab in first year engineering leads to increased conceptretention.

Overall control ofthe system is achieved using a microcontroller, in this case an Arduino UNO.
