Solved: In 710, a string of length L coincides with the interval [0, L] on the x-axis
Chapter 13, Problem 10(choose chapter or problem)
In Problems 7-10, a string of length L coincides with the interval [0, L] on the x-axis. Set up the boundary-value problem for the displacement u(x, t).
The ends are secured to the x-axis, and the string is initially at rest on that axis. An external vertical force proportional to the horizontal distance from the left end acts on the string for t>0.
