Mines was doing the same thing and the solution was to replace the front U-joint. Its fine now.
the lower the sound
The larger an instrument is, the more room inside it there is for air to vibrate. Because there is more space, it takes the vibrating air longer to vibrate through the entire instrument, which slows the overall vibration rate down. Slower vibration= lower pitch.
Shorter strings vibrate at a higher frequency than longer strings.
Vibrating brakes are almost always a symptom of worn rotors. When the rotor wears down, or has grooves, the brake pad can no longer make a flush connection with the rotor. This will cause the caliper (which holds the brake pad) to move in and out as it tries to establish a flush connection with the rotor. The rapid movement of the caliper is what causes your brake pedal to vibrate.
Making a string longer with the same position where it's held(like a violin) should make it less tense, making it vibrate slower, therefore lower.
Theory
None. The column of air inside the instrument vibrates. Compare this to a string instrument -- the string vibrates, of course. With the reed instrument, such as a clarinet or bassoon -- the reed vibrates. The vibrating reed causes the column of air inside the instrument to vibrate. However, the brass instruments do not have vibrating parts. What makes the column of air vibrate is the buzzing of the player's lips!
Hey ya i have a 1994 grand am and i was having this same problem. What i did what replace the spark plugs. After i did this i took the car and and when i floor it no longer stutters when accelerating.
The reason that they create longer notes is because it vibrates faster, but not as big vibrations, which causes the pitch to be higher, and also can vibrate longer.
true
The vocal cords (in the throat) vibrate. Longer and thicker ones, as men have, produce deeper sounds.
Terminal velocity- When a falling object is no longer accelerating; the force due to gravity is equal to the opposing force of air resistance.
