A control pedal of an aircraft can be modeled as the single-degree-of-freedom system of Figure P1.69. Consider the lever as a massless shaft and the pedal as a lumped mass at the end of the shaft. Use the energy method to determine the equation of motion in θ and calculate the natural frequency of the system. Assume the spring to be unstretched at θ = 0 and gravity points down.
