In a single degree of freedom vibrating system, the concentrated mas which weighs 38.6 lbs. is acted upon by a disturbing force f(t)=50sin(20pi*t). If the spring constant is 400 lb./in. and the damping coefficient is 4 lb-sec/in, calculate the frequency ratio, the damping ratio(factor), the lag angle, the amplitude of the vibration, and the maximum force transmitted to the foundation.
