+ b 3. A tuning fork is an example of a "resonant system", that is, one that has a low damping ratio. A model of a (half) tuning fork is rod of mass m with air drag modeled as a damper connected approximately at its middle, and a torsional spring at the base of the cantilever. Assume the cantilever rotates back and forth about its pivot by a small angle o. Because other forces are much larger, you can reasonably neglect the effect of gravity in this model. The moment of inertia of a cantilevered beam pinned at one end is equal to ml2, where I is its length.

QUESTION 3. Consider the mass-spring oscillator without friction: y" + y = 0. Suppose we add a force x(t) which corresponds to a push (to the left) of the mass as it oscillates. We will suppose the push is described by the function x(t) = -u(t – 2n) + u(t – (2n + a)) for some a > 2n which we are allowed to vary. (A small a will correspond to a short duration push and a large a to a long duration push). Here, u(t) is the unit step function. We are interested in solving the initial value problem y" + y = x(t), y(0) = 1, y'(0) = 0.
