True or False: Write your answer after the question.1. The root cause of vibration is balanced forces in the machines.2. A motion that repeats itself after an equal interval of time is known as periodic Motion.3. If the vibratory system has no damper, then the vibration is called damped vibration.4. The simple harmonic motion can be expressed by the equation x=Asinwt.5. When the shaft particles move parallel to the axis of the shaft, then the vibrations are known as longitudinal vibration.6. When the shaft particles move approximately perpendicular to the axis of the shaft, then the vibrations are known as transverse vibration.7. Vibration occurs when a system is displaced from a position of unstable equilibrium.8. Frequency is the time it takes to complete one loop. 9. The free vibrations continue indefinitely in an ideal system as there is no damping.10. Self-excited vibrations are periodic and deterministic.
