Chapter 9: Problem 1
Determine the scalar product of the functions \(f(x)=\cos (2 n \pi x / L)\) and \(g(x)=\cos (2 p \pi x / L)\) on the domain \(0 \leq x \leq L\), where \(n \neq p\) are positive integers greater than zero.

Get started for freeState the governing equation and boundary conditions for transverse motion of the active segment of a guitar string of mass density \(\rho\) and cross- sectional area \(A\) that is under static tension \(N\), when a musician presses on the string with his finger at a fret located a distance \(L\) from the bridge. The stiffness of the musician's finger is \(k\).
Show that, for the case of lateral motion of the support of a beam, the linearized version of Eq. (9.189) converges to \(\mathrm{Eq}\). ( \(9.104\) ) for proper change of variables. (Hint: Note that in Example \(9.9\) w corresponds to "absolute displacement.")
State the equation of motion and boundary conditions for torsional motion of an elastic rod that is fixed at on end and is attached to a rigid disk of mass moment of inertia \(I_{D}\) at its free end.
