A video camera, of mass 2.0 kg, is mounted on the top of a bank building for surveillance. The video camera is fixed at one end of a tubular aluminum rod whose other end is fixed to the building. The wind-induced force acting on the video camera, f(t), is found to be harmonic with f(t) = 25 cos(75.3984t) N. Determine the cross-sectional dimensions of the aluminum tube if the maximum amplitude of vibration of the video camera is to be limited to 0.005 m. Ealuminum = 71 GPa, Itubular bar = dt(d + t), assumed = 10t.
