A shaking table working in frequency f = 0 〜 150 Hz is utilized as a frame on which small size of vibrationdevices may set in forced vibrations. A cantilever set up on the table may yield resonance when the shaking frequencygoes to the natural frequency of the cantilever which depends on material, length, diameter and fine geometrical configurations.A simple pendulum on the table makes free vibration when f = 0, while it yields parametric vibrations whenf ̸= 0. Depending on the shaking amplitude, linear or nonlinear vibrations may arise on the pendulum. Some combinationof vibration devices may then provide coupling vibrations and chaotic ones for which much attention has been paidin recent years. We study free vibrations of Blackburn pendulum (`Y' shape pendulum) and `V' shape pendulum, andthen the parametric and forcing vibrations of Blackburn pendulum. On account of the vibration phenomena observed,education materials with experiments, measurement system and numerical simulation are now realized as a cooperativeeducation project on various crossover engineering fields, which will be expected to extend further beyond departmentsor colleges for engineering education.
