In Example 7, change 1.14 N to 1.35 N and then solve the resulting problem.

Data from Example 7

The frequency f of vibration of a wire varies directly as the square root of the tension T of the wire. If f = 420 Hz when T = 1.14 N, find f when T = 3.40 N. The steps in making this evaluation are outlined below:

f = kT 420 Hz = kV1.14 N k = 393 Hz

We note that k has a set of units associated with it, and this usually will be the case in applied situations. As long as we do not change the units that are used for any of the variables, the units for the final variable that is evaluated will remain the same.

f = kT 420 Hz = kV1.14 N k = 393 Hz /N1/2 f = 393T f = 3933.40 = 725 Hz
