Q1. The natural frequency of vibration of a person is found to be 5.2 Hz while standing on a horizontal floor. Assuming damping to be negligible, determine the following: a. If the weight of the person is 70 kgf, determine the equivalent stiffness of his body in the vertical direction. b. If the floor is subjected to a vertical harmonic vibration of frequency of 5.3 Hz and amplitude of 0.1 m due to an unbalanced rotating machine operating on the floor, determine the vertical disnlacement of the person

standing on a horizontal floor. Assuming damping to be negligible, determine the
following:
a. If the weight of the person is 70 kgf, determine the equivalent stiffness of his body
in the vertical direction.
b. If the floor is subjected to a vertical harmonic vibration of frequency of 5.3 Hz and
amplitude of 0.1 m due to an unbalanced rotating machine operating on the floor,
determine the vertical displacement of the person.
