 A mass of 50 kg suspended from one end of a helical spring, the other end being fixed. The stiffness of the spring is 100 N/m. The resistance of air damping is given as 0.1 N/m/s vibrating freely at its natural frequency of 10 rad/s. What will be the magnification factor at resonance of the spring?
