1. The problem statement, all variables and given/known data [PLAIN]http://img441.imageshack.us/img441/6951/physics.gif [Broken] As shown in the figure, one end (O) of a uniform rod of length L and mass M is pivoted to a wall. Two horizontal springs with force constants k1 and k2 are attached to the other end (P) of the rod. When the rod is aligned exactly along the vertical axis, the system is in equilibrium. a) Find the period of small oscillations of the rod. b) Assume that the initial angle the rod makes with y-axis is a small angle θ and the initial velocity 0. Find the velocity of the end point P of the rod as it passes through the equilibrium position. 2. Relevant equations Moment of inertia of a rod relative to its end: I = 1/3 ML2 3. The attempt at a solution I think I have a solution but it is too long and complex. I doubt it's correct. Any help appreciated.
