MEE444 HOMEWORK # 16 25 MAY 2025 In a highway expansion joints at a distance of 13.73 m apart cause a series of impulses at equal intervals to effect cars traveling at a constant speed. Consider these joints as shown in the figure. Assume that a car in HW 15 has a up and down natural frequency of 7.00 rad/sec (in x-direction), and a pitching natural frequency of 9 rad/sec (about $\theta$ direction). Determine the speeds of car at which pitching motion and up and down motion will be felt inside the automobile. Joints Assumed highway shape L=13.73m

Step 1

73$ m. Natural frequency for up and down motion (heave), $\omega_{n,heave} = 7.00$ rad/sec. Natural frequency for pitching motion, $\omega_{n,pitch} = 9.00$ rad/sec. The problem asks to find the speeds of the car at which resonance occurs for both heave and Show more…
