A bar of mass m is suspended horizontally on two vertical springs with the force constants k and 3k. The bar bounces up and down while remaining horizontal. Find the period of oscillations of the bar. Neglect the mass of the string that connects the springs and the friction between the string and the pulley.
We received a large number of solutions from all over the world for our September Challenge, Slipless in Seattle. We are pleased to recognize the following contributors:
