2015年5月31日 · The tension being zero is right at the moment of transition between the string being taut and the string being slack; usually in "particle on a string" problems you have to find the minimum or maximum of some value, and usually the trick is to take the tension equal to zero as this is where the string is "barely" taut.

A taut string (string 1) pulls upward on a 6 kg block. A 2 kg block hangs from the 6 kg by another taut string (string 2) which pulls upward on the 2 kg block with a force of 12 N. The magnitude of the net force on the 6 kg block is N. ↑ string I 2 string 2

When you pluck a guitar string the potential you apply to the string is approximately a Dirac delta function. That is to say, the release of the string is a near instantaneous kick. One of the beautiful properties of the delta function is that its Fourier transform is unity. This means that it is made up of equal components of all frequencies.

A 2 kg block hangs from the 6 kg by another taut string (string 2) which pulls upward on the 2 kg block with a force of 12 N. The tension in string 1 is. N. ↑ string | string 2 2 The answer is 48, pls explain how

Two transverse waves travel along the same taut string. Wave 1 is described by y 1 (x, t) = A sin (kx -ωt), while wave 2 is described by y 2 (x, t) = A sin (kx + ωt + φ). The phases (arguments of the sines) are in radians, as usual, and A …

2015年2月5日 · A wave on a string is like a harmonic oscillator (think mass on a spring). The oscillation happens because of the interplay between the restoring force, which tries to bring the mass to equilibrium, and the inertial quality of the mass, which tends to overshoot equilibrium. If you take away either, you don't get an oscillation.

2017年4月25日 · $\begingroup$ Excellent. So with this in mind I read over someone who posted the following: "The tension being zero is right at the moment of transition between the string being taut and the string being slack; usually in "particle on a string" problems you have to find the minimum or maximum of some value, and usually the trick is to take the tension equal to zero as this is where the string ...

2023年10月10日 · The accelerations of the two ends of the string are only equal as vectors if the string is both taut and straight throughout the motion. The accelerations of the two ends of the string will be equal in magnitude (although not necessarily in direction) if the string is taut and follows a fixed path. This is justified by geometry, not dynamics ...

The wave function for a traveling wave on a taut string is (in SI units) y (x, t) = 0.360 sin (13 π t − 2 π x + 4 π ) (a) What are the speed and direction of travel of the wave? speed Your response differs from the correct answer by more than 10%. Double check your calculations.
