Awater tower is idealized as a mass m on top of a uniform and massless beam. the bottom end of the beam is fixed to the ground. the beam has solid circular cross section with a diameter of 1.2 m. its young’s modulus is 30 gpa, and its length is 10 m. the mass m is 20 tons. find the natural frequency and natural period of this system in lateral oscillations.
