COURSE OUTCOMES:
for each course outcome, links to the Course Objectives are identified in brackets.
  1. Investigate how to compare the mathematical model of a dynamic system with its experimental performance [1, 2]
  2. a. Evaluate the thermal efficiency and cooling capacity of a vapor compression cycle, evaluate the effectiveness of the condenser and evaporator, and evaluate the isentropic efficiency of the compressor over a range of operating conditions [1, 2]. b. Experimentally measure the frequency response of a subwoofer speaker, obtain a simplified model of the speaker through 'curve fitting,' design a feedforward compensator, design a feedback/feedforward compensator, implement the compensators using analog circuits, and verify the performance of the compensated speaker [1, 2]
  3. a. Determine the thermal and mechanical efficiency of a single cylinder engine. Compare indicated and brake engine power. Evaluate the effect of air/fuel, load, and compression ratios on engine performance and emissions. Evaluate engine losses due to friction [1, 2]. b. Determine how clamping force and injection pressure influence the outcome of an injection molding process. Examine the dimensional stability of injection molded parts. Determine the residual stresses and flow patterns in clear parts using optical methods. Examine how process parameters influence the mechanical strength of weld lines [1, 2]. c. Determine how welding process parameters such as feed rate and input power influence the heat effected zone for MIG and spot-welding processes. Section and microscopically examine the welded zone. Determine how process parameters influence the strength of the welded joint [1, 2]
  4. Create a proposal for an experimental program [3]
  5. Plan and execute an experimental program [3]
  6. Be able to use a variety of industrial and scientific formats to present the results and conclusions of an experimental project in a clear, readable, succinct, and informative written format [4]
  7. Present a proposal for a project in an oral form [5]
  8. Present the results of a project in a poster format [6]
