Example: Find the effective spring constant of multiple springs connected in series Example: Find the effective spring constant of multiple springs connected in parallel Find the effective spring constant of infinitely many identical springs attached in parallel as shown. 1,2,4,8,.... infinitely many springs Each has the same spring constant k Fing the angular frequency of small oscillations in the vertical plane of the stick with length l and mass m that is held in equilibrium between two identical horizontal springs Fing the angular frequency of small oscillations in the vertical plane of the stick with length l and mass m that is held in equilibrium between two identical horizontal springs To observe oscillations A hexagonal frame, which can rotate freely with respect to the center of mass, has sides of length l and mass m, is attached as shown in the figure by means of a spring with constant k. What is the period of the small vibrations of the system? A stick of length l will be pivoted such that it is free to rotate in the page plane around the axis perpendicular to the page. Where should the stick be pivoted such that the angular frequency of small oscillations is maximized?
