- Observe the phenomenon of whirling and measure/extract modal parameters at resonance in order to explain failure due to resonance (or excessive vibration).
- Measure the radius of curvature of a bent beam using the beam bending test.
- Measure the critical loads of columns with various end conditions using column buckling test.
- Determine failure due to creep by generating the extension-time curve and extracting creep constants from experimental data and explain the creep phenomenon.
- 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.
- Measure the torque-twist relation and determine material constants (Young's modulus and shear modulus) using the tensional test.
- Measure the material properties (Young's modulus, yield stress, ultimate stress, breaking stress) of a sample using the Tensile Test.
- Describe the scope of fluid mechanics.
- Calculate the hydrostatic forces, pressures and moments on planar and curved submerged and floating surfaces.
- Decide when it is appropriate to use ideal flow concepts and the Bernoulli equation.
- Construct an appropriate control volume for a given engineering system and apply the principles of conservation of mass, momentum, and energy to this control volume in differential and integral forms.
- Solve for internal flow in pipes and channels through simple solutions of the Navier-Stokes equations, the Moody chart and the head-loss equation.
- Solve for external (laminar and turbulent boundary layer) flows, evaluate lift and drag, know when there is possibility of flow separation.
- Work in teams to conduct experiments effectively and efficiently.
- Compile, analyze and interpret collected experimental data and prepare technical reports.
