Question

Solve the wave equation, subject to the conditions cited in the problem.

The longitudinal displacement of a vibrating elastic bar shown in the figure satisfies the wave
a'u d'u
equation a
0<x< L, t> 0 and the conditions:
du
du
= 0,
ax
x L
= 0,
t> 0
ax
x = 0
du
u(x, 0) = x,
= 0,
0 < x < L.
t= 0
Hu(x, 1)
The boundary conditions at x = 0 and x = L are called free-end conditions.
Find the displacement u (x, t).
