Question 4: Consider a vibrating string with governed by the wave equation /14 $\frac{\partial^2 \tilde{y}}{\partial t^2} = c^2 \frac{\partial^2 \tilde{y}}{\partial x^2}$ The string is pinned at both ends, meaning $\tilde{y}(x = 0, t) = 0$ $\tilde{y}(x = L, t) = 0$ (a) Determine the general solution to this PDE, check all eigenvalues. /10 (b) The string is struck so that the initial velocity is $\frac{\partial \tilde{y}}{\partial t}(x, t = 0) = 1 \sin(\pi x/L)$ m/s. Sketch and describe the solution. /4

Part 1: Draw the FBD & MAD for the compound pendulum (mass = m, mass-moment-of-inertia about centroid = I, mass-moment-of-inertia about pivot = I). Sum moments at the pivot to derive the equation of motion. (This is Newton's method). Assume θ is small. Extract the natural frequency. Use dimensional analysis to determine the period T. Rearrange the resulting equation to create two equations which give you: - The mass moment of inertia about the centroid: I - The mass moment of inertia about the pivot: Io Part 2: Write the kinetic energy of the compound pendulum T, and its gravitational potential energy U. Maximize each. (Recall: since θ = θmax * cos(ωnt) then θmax = θ0. Also, angular velocity is ω = ωn * sin(ωnt) so ωmax = ωn) Set Tmax equal to Umax and solve for the natural frequency ωn. (This is the energy method. Expect the amplitude θ0 to drop out! Now proceed as in part 1 to generate the equations for I & Io)
