(a) How much will the piston descend after the weights are added? Assume an isothermal process. (b) What will the final pressure in the cylinder be? (c) Should heat be transferred in or out of the cylinder during this process?Exercise 2: Now we’ll charge the cylinder and use it to lift a 20 lb weight. The accumulator actslike a capacitor, storing energy for us until we need it. First, we’ll charge the cylinder to ___ psig(will be around 85 psig). Then we’ll attach the tube to the piston cylinder lower port. A valveinitially separates the accumulator from the piston cylinder. (a) How much

outcome was measured in two ways.Firstly, a learning survey instrument was used (See Appendix B). Secondly, a standardassessment based on examination results was used. A control sample consisting of a previousclass taught by the same instructor was used. The control sample size was also 12 students;approximately 50% of the annual student population of the course as with the experimentalsample.The exams consisted of the same problems for both samples and were graded by the same graderwith the same style and standards. In the authors’ opinion, the experimental group did not haveaccess to those same exam problems given to the control sample. If the experimental group hadaccess to the exam problems (which would also imply that the ideal solutions

, debugging, and software training. Acourse in programming can be challenging for many students choosing to major in mechanicalengineering. The major attracts students with diverse backgrounds and a wide variety ofacademic interests. It is uncommon for students to choose to study mechanical engineeringbecause of their interest in programming or modeling. This often leads to a disconnect betweenthe students and the instructor, which can create an intimidating classroom environment. Thework presented here is driven by these findings.A new programming course has been developed to address the problems existing in the originalcourse model, which include: (a) the course being offered outside of an engineering department,(b) the extreme variability in the

They are encouraged to identify problems from their work experience, and those that might be useful to their company (if they are not confidential). They are also notified that this is a required first task of the course for credit. Each student needs to submit this list along with sketches via email, but no later than the first day of classes.

It can simulate the motion of alinkage, and display specific linkage analysis functions such as transmission angle, angularvelocity ratios, locations of instantaneous centers of rotation, and mechanical advantage (staticforces which can be compared to the dynamic force calculations). Once the kinematic model ofthe car suspension system has been built up in the FOURBAR program, the model is simulatedto determine the suspension kinematics and view the path of the instant center over some rangeof motion to provide a clear picture of the behavior of the coupler link. Also, the motionparameters can be easily changed to visualize such output motions as displacement, velocity andacceleration in

thestudents by informing them about what engineers do So in order to give students an opportunity to receive this much-needed exposure to real-world problems, an instructional strategy was developed. This strategy used real-world casestudies developed by the Laboratory for Innovative Technology and Engineering Education(LITEE) at Auburn University. This paper discusses how these case studies have been used to (a)develop specific student capabilities and (b) help students learn certain engineering principles Page 15.1307.2and apply them to solve problems occurring in real-world situations.Case Study: A case study typically is a record of a

Table 1 shows thedistribution of all grades for the 10 students who have completed the course to date (the 11thstudent is currently taking the course). Note that ‘Law’ refers to the grade earned relative toother law students; ‘Eng’ refers to the grade given using the engineering curve. The range ofgrades earned by the law students is typically A to C-. The law school also requires that classeswith more than 10 students have a B median. The intellectual property class taken by theengineering students always falls into this category. A A- B+ B B- C+ C C- Law 0

Meeting all of the objectives results in a score of 90%, which is the line between an “A” and a “B” at Grove City College. • Students are required to do excellent work and exceed their objectives if they want to achieve an “A”. • Students are likely to miss an objective or two, especially if the objectives are aggressive.Required Objectives Score= [(a x 100)+(b x 90)+(c x 75)+(d x 40)]/4 where: a = #Exceeded b
