Determine the natural frequency of the system which is shown below. Here, springs geometries are similar but spring 1 is made of mild steel, spring 2 is made of copper, d = 5 mm, spring index = 10, number of active coils in the springs = 8, m2 = mo, r2 = r1 = 25 mm = 0.4R = 5t and the pulleys are made of cast iron. Take other information which is necessary to solve the problem from the internet/literature/book.
