2) As shown in the figure, a uniform rod of length I and mass m is supported by a pin at one end and is suspended horizontally from a string of length h at a point s from the end. m 1/2 $ G: Ah h 真横からみた図 1) When the string rotates by 0, how much does the position of points on the rod move upward? (Just the answer is enough.) 2) When the string is displaced upward by Ah, how much does the bar's center of gravity displace? (Just write your answer). 3) Find the change in potential energy U at this time. Next, assuming that is small, express U as a power of 0. 4) Find the moment of inertia of mass m around the fulcrum. 5) Find the kinetic energy when the rod rotates by around the fulcrum. Using the relationship h0 = so, express the kinetic energy as the power of the derivative of 0. 6) Find the natural angular frequency of this system using the energy method.
igure 2. Assume that the rod is massless, perfectly rigid, and pivoted at point P. When the rod is perfectly horizontal, the angle 0 = 0, the displacement y 0, and the springs are in neither tension nor compression. Gravity acts on the system (e.g. on mass M). We assume that y is a small displacement. A mass M is attached at the end of the rod.
