13.6.21. On body mass m = 10 kg, which is suspended from a spring with a stiffness coefficient = 150 N / m, acting vertical exciting force F = 10sin pt strength and resistance R = -8v. Determine the maximum amplitude of the steady-state oscillation, which can be achieved by changing the value of the angular frequency of the driving force.
