A rotor blade of a helicopter has a constant cross-section of 1cm x 20 cm and a length of 0.7m. The material of the blade is aluminum, for which Young's modulus is 70 GPa and the density is 2800 kg/m3. Use a system with a single degree of freedom to determine the fundamental natural frequency(rad/s), frequency (Hz), and period (s) of the blade.
