CE 137 ACTUAL EXAM 1WELL ELABORATED WITH Q&A 2024/2025 when does transition from oscillatory to non- oscillatory take splice? - CORRECT ANSWER damping ratio = 1 type of damping (damping ratio = 1) - CORRECT ANSWER critically damped type of damping (damping ratio 1) - CORRECT ANSWER overdamped type of damping (damping ratio 1) - CORRECT ANSWER underdamped what type of damping returns to its equilibrium at a slower rate but does not oscillate - CORRECT ANSWER overdamped? dynamic test used to determine the damping ratio of a structure experimentally - CORRECT ANSWER free vibration test type of loaf that exhibits simple harmonic motion - CORRECT ANSWER harmonic load vibration caused by the action of external dynamic excitation - CORRECT ANSWER forced vibration vibration caused by initial condition - CORRECT ANSWER free vibration if the forcing frequency is less than the natural frequency, the motion is said to be (in-phase / out-of-phase) - CORRECT ANSWER in- phase phase angle of forcing frequency is less than the natural frequency - CORRECT ANSWER 0 degrees phase angle of frequency greater than the natural frequency - CORRECT ANSWER 180 degrees when does transition from oscillatory to non- oscillatory take splice? - CORRECT ANSWER damping ratio = 1 type of damping (damping ratio = 1) - CORRECT ANSWER critically damped type of damping (damping ratio 1) - CORRECT ANSWER overdamped type of damping (damping ratio 1) - CORRECT ANSWER underdamped what type of damping returns to its equilibrium at a slower rate but does not oscillate - CORRECT ANSWER overdamped? dynamic test used to determine the damping ratio of a structure experimentally - CORRECT ANSWER free vibration test type of loaf that exhibits simple harmonic motion - CORRECT ANSWER harmonic load vibration caused by the action of external dynamic excitation - CORRECT ANSWER forced vibration vibration caused by initial condition - CORRECT ANSWER free vibration if the forcing frequency is less than the natural frequency, the motion is said to be (in-phase / out-of-phase) - CORRECT ANSWER in- phase phase angle of forcing frequency is less than the natural frequency - CORRECT ANSWER 0 degrees phase angle of frequency greater than the natural frequency - CORRECT ANSWER 180 degrees
