Outcomes
- Operate and explain the function of typical mechanical systems, such as cam-follower systems and planetary gear trains
- 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
- Calculate and measure the speed reduction and the efficiency of planetary gear systems, and to observe the effect of design configuration on the efficiency
- Calculate heat transfer rate and temperature distribution in steady-state one-dimensional heat conduction problems
- Calculate the rate of steady heat transfer in fins, and unsteady heat transfer in lumped-capacitance and semi-infinite solid problems
- Explain the terms in the governing equations for convective heat and mass transfer
- Estimate convective transfer rates on the basis of geometric and dynamic similarity, and analogy between different convective transport processes
- Calculate heat and mass transfer rates in external and internal flows, including flat plates, cylinders, pipes, heat exchangers, and free convection at vertical surfaces
- Apply the laws of radiation to compute heat transfer rates for surfaces, such as black bodies and diffuse gray surfaces, with appropriate approximations
- Calculate and use the view factor for simple surface combinations, and the total emissivity for surfaces
- Estimate grain size of sample materials manually using optical microscope, digital data acquisition system, and software image editing
- Measure the material hardness using Rockwell Hardness Test and apply the Hardness conversion table
- Work in teams to conduct experiments effectively and efficiently
- Compile, analyze and interpret collected experimental data and prepare technical reports
