![Figure below shows a rod with mass M = 100 kg, cross section area A = 10 cm². The rod is supported by 4 springs having stiffnesses of
k = 1 MN/m. A tip mass with m = 120 kg is attached to the rod. Assume x is the degree of freedom of the equivalent system. The Young's
modulus, E, is not known. If the natural frequency of the equivalent mass-spring system is 40 Hz, determine the Young's modulus, E.
Assume the length of the rod is L = 5 m. Find the nearest answer.
