A one-story reinforced concrete building has a roof mass of 500 kips/g, and its natural frequency is 4 Hz. This building is excited by a vibration generator with two weights, each 50 lb, rotting about a vertical axis at an eccentricity of 12 in. When the vibrator generator runs at the natural frequency of the building, the amplitude of roof acceleration is measured to be 0.02g. Determine the damping of the structure. Neglect the mass of the structure except for the roof mass.

11.7 (A/B). A solid shaft carrying a flywheel of mass 100 kg and radius of gyration 0.4m rotates at a uniform speed of 75 rev/min. During service, a bearing 3 m from the flywheel suddenly seizes producing a fixation of the shaft at this point. Neglecting the inertia of the shaft itself determine the necessary shaft diameter if the instantaneous shear stress produced in the shaft does not exceed 180 MN/m². For the shaft material G= 80 GN/m². Assume all kinetic energy of the shaft is taken up as strain energy without any losses. [22.7 mm.]
