Suppose you become famous because you were able to develop a non - contact way of measuring tension in suspended wires. Your method would be based upon which physical insight below?
A) The frequency of a vibrating string depends on the tension in the wire, and so a frequency measurement will determine tension.
B) The velocity of a wave depends on the height of the string above the ground, and so by measuring velocity we can get the wire's shape which will tell us how tense it is.
C) Greater tension causes lower pitches and so all we have to do is to measure the pitch of the vibrating wire to get he tension.
D) Tension depends upon the wire's temperature and so we just make a temperature measurement.

Question

Quizplus · Accepted Answer

The frequency of a vibrating string or wire is directly related to the tension in the wire. By measuring the frequency of vibration, one can determine the tension in the wire without needing to make contact with it. This principle is used in various applications, including musical instruments and engineering diagnostics. Options B, C, and D do not accurately describe the relationship between tension and measurable properties of a wire in the context of non-contact measurement.
