At a certain engine speed, a car's wing mirror starts to vibrate strongly. This is an example of resonance. Explain what is meant by resonance and why it occurs in this situation.

49. John visits a space camp during the summer break. During this visit, John sits in a chair mounted to springs which undergoes simple harmonic motion. During this time, the motion is measured electronically and zaim's mass, along with the mass of the chair are taken into account. John notes the spring has a spring constant of 516N/m and the mass of the chair is 26.0 kg. If the period of oscillation zaim notes is 2.31 s what is John's weight? A 69 kg 44 kg 57 kg D 82kg E 77 kg B

Two successive frequencies of harmonic vibration (reasonance) in a pipe are 532HZ and 684Hz. Is the pipe open at both ends or closed at one end?  I'm just trying to conceptually understand this. Thank you for your help.

Your car rides on springs, so it will have a natural frequency of oscillation. as shown data for the amplitude of motion of a car driven at different frequencies. The car is driven at 20 mph over a washboard road with bumps spaced 10 feet apart; the resulting ride is quite bouncy. Should the driver speed up or slow down for a smoother ride?

In the figure, two blocks (m = 2.40 kg and M = 12.5 kg) and a spring (k = 280 N/m) are arranged on a horizontal frictionless surface. The coefficient of static friction between the two blocks is 0.320. What amplitude of simple harmonic motion of the spring-blocks system puts the smaller block on the verge of slipping over the larger block? %3D 00000000 M Number Units

A squirrel is standing on an overhead telephone cable. At one end of the cable is a sensorthat can record small vibrations. If the squirrel begins to run toward the sensor, such thateither its front legs or hind legs land on the cable every 0.1 seconds, what frequency willbe detected by the sensor?(A) exactly 0.1 Hz(B) between 0.1 Hz and 10Hz(C) exactly 10 Hz(D) slightly more than 10 Hz

Q22: The figure shows a vibration signal from a displacement transducer. The amplitude of the acceleration is (a) 2760 m/s² (b) 1380 m/s2 (c) 4.39 m/s² (d) 2.20 m/s² (c) None of the above ANS: B Displacement (mm) 0.02 0.04 Time (s) 0.00 0.08 0.1
