A string of length L, mass per unit length mu, and tension T is vibrating at its fundamental frequency. What effect will the following have on the fundamental frequency? The length of the string is doubled, with all other factors held constant. The mass per unit length is doubled, with all other factors held constant. The tension is doubled, with all other factors held constant.

A stretched string has a mass per unit length of 4.82 g/cm and a tension of 12.9 N. A sinusoidal wave on this string has an amplitude of 0.150 mm and a frequency of 168 Hz and is traveling in the negative direction of an x axis. If the wave equation is of the form y(x,t) = ym sin(kx + ωt), what are (a) ym, (b) k, and (c) ω, and (d) the correct choice of sign in front of...

1. A uniform horizontal beam OA, of length a and weight w per unit length, is clamped horizontally at O and freely supported at A. The transverse displacement y of the beam is governed by the differential equation d2y El dx2 w(a x)- R(a - x) where x is the distance along the beam measured from O, R is the reaction at A, and E and I are physical constants. At O the boundary conditions are dy (0) = 0....

Wave on a String A string with linear mass density 2.0 g/m is stretched along the positive x-axis under a tension of 20 N. The other end of the string, at x = 0m is tied to a hook that oscillates up and down at a frequency of 100Hz with a maximum displacement from equilibrium of 1.0 mm. At t= 0s, the hook is at it's lowest point. (a) What are the wave speed and the wavelength on the string?...

1. The total kinetic energy of the vibrating string is given by the integral (a) Why does this integral give kinetic energy? (b) The potential energy V(t) of a stretched string originates in the work done against the tension T when as a result of its displacement, the string becomes longer. Show that (c) Use the series expression (3.16b if Nettel) to show that the total energy can be written as a sum over normal mode terms, with no cross-terms...

If the mass per unit length of a violin string was quadrupled without changing the string's tension, the speed with which a wave (produced by the player's bowing action) travels on that string would -become four times its former value. -become one half of its former value. -become two times its former value. -become one quarter of its former value. -not change.

A tension FT is applied to a wire with mass per unit length μ and length L. When struck, it vibrates at its fundamental frequency f1. The wire is then removed and stretched to twice its original length 2L. If the same tension is applied to the stretched wire, what will be its new fundamental frequency?
