VIBRATION ENGINEERING ASSIGNMENT#2
1. Consider the crank-mechanism system shown below. Determine the rotary inertia of this system about
the point O and express it as a function of the angular displacement u. The disc has a rotary inertia JG
about the point 0. The crank has a mass mgand rotary inertia Jg about the point G at the center of
mass of the crank. The mass of the slider is m,
2. Determine the number of degrees of freedom used in the analysis of the mechanical system. Specify
the set of generalized coordinates that can be used in the system's vibration analysis.
3. Express the kinetic energy of each of the systems and determine the number of degrees of freedom of
each system in terms of the specified generalized coordinates.
