ME 461 Mechanical Vibrations Fall 2014 Preparation for Mini-exam #4 Reading: • Chapter 3, sections 5, 6, 11 (repeated from previous assignment) • Chapter 4, sections 1, 2 (new reading) Homework: • Chapter 3: support motion/isolation: 3.20, 3.21, 3.25, 3.28; measuring devices: 3.43, 3.45, 3.47 (all repeated from HW #3) • Chapter 4: 4.1 and 4.2 (new, exercises in calculus to determine the time and amplitude of the peak of the impulse response – you should plot these versus the damping ratio for future reference and problem solving) • Three from the book, Engineering Vibration, by D. J. Inman, 3 rd ed., Prentice Hall, 2008: • Problem A: The system has m=3.0kg, k=2.0 X 10^5 N/m, the design constraint is 0.01m max deflection, and note that the bird does not stick to the camera after hitting it.

ME 461 Mechanical Vibrations Fall 2014 Preparation for Mini-exam #4 Reading:
• Chapter 3, sections 5, 6, 11 (repeated from previous assignment) • Chapter 4, sections 1, 2 (new reading)
Homework:
• Chapter 3: support motion/isolation: 3.20, 3.21, 3.25, 3.28; measuring devices: 3.43, 3.45, 3.47 (all repeated from HW #3)
• Chapter 4: 4.1 and 4.2 (new, exercises in calculus to determine the time and amplitude of the peak of the impulse response – you should plot these versus the damping ratio for future reference and problem solving)
• Three from the book, Engineering Vibration, by D. J. Inman, 3rd ed., Prentice Hall, 2008:
• Problem A: The system has m=3.0kg, k=2.0 X 10^5 N/m, the design constraint is 0.01m max deflection, and note that the bird does not stick to the camera after hitting it.
• Problem B: Here you are to ignore the rotation of the wheel, just
consider its vertical response.
• Problem C:
