Motion of bicycle = rotary 2. Moves around fixed axis = circular motion 3. ½ vibration = beat 4. 1N = 10 dynes / 100,000 dynes 5. Impulse = kg.m/sec 6. Periodic time simple harmonic = inversely 7. Motion particle with simple harmonic = one oscillation 8. Simple pendulum = 2π√(l/g) 9. Damping ratio less than 1 = underdamped 10. Damping ratio equal to 0 = undamped 11. Maximum displacement of forced vibration = magnification factor 12. Resistance of material = stiffness 13. For two springs = F = y/l 14. Reduction in amplitude = damped vibration 15. Longitudinal vibrations = parallel to axis 16. Subjected to transverse vibrations = tensile 17. Natural frequency in (Hz) = (1/2π)√(g/l) 18. Affects critical speed = all of choice 19. CC > 1 = overdamped 20. CC = 1 = critically damped 21. Motion of particle = simple harmonic 22. Number of freedom & continuous = infinite 23. Degree of freedom is number of independent displacements 24. Time period (T) = 2π/ω 25. Shock absorbers = critical damping 26. Rayleigh's = conservative force 27. Stretched wires = forced transverse 28. Forced vibrations = free vibrations 29. SHM = displacement 30. Harmonic oscillator = elliptical 31. Maximum displacement = amplitude 32. Critical damping depends on mass & stiffness 33. Factor to be unity = critically damped Read more
