  1. Operate and explain the function of typical mechanical systems, such as cam-follower systems and planetary gear trains [a, b].
  2. Measure and explain the effect of design parameters on system dynamics and performance, including the effect of cam profile on the dynamics of a cam-follower system and the effect of unbalance on the performance of a rotor [a, k].
  3. Calculate and experimentally measure the speed reduction and the efficiency of planetary gear systems, and to observe the effect of design configuration on the efficiency [a, b].
  4. Measure the effect of design parameters (i.e. material strength) and operating conditions (i.e. magnitude of cyclic load) on the lifetime of machine elements subject to fatigue and explain the failure due to fatigue [a, b].
  5. Determine failure due to creep by generating the extension-time curve and extracting creep constants from experimental data and explain the creep phenomenon[a, b].
  6. Observe the phenomenon of whirling and measure/extract modal parameters at resonance in order to explain failure due to resonance (or excessive vibration) [a, b].
  7. Work in teams to conduct experiments effectively and efficiently [g].
  8. Collect, process, and analyze data, and write lab reports to document experimental work [g, b].
