The human leg can be compared to a physical pendulum, with a"natural" swinging period at which walking is easiest. Consider theleg as two rods joined rigidly together at the knee; the axis forthe leg is the hip joint. The length of each rod is about the same,55 . The upper rod has a mass of 7.3 and the lower rod has a mass of4.3 .
Calculate the natural swinging period of thesystem.
