A valve of piston type has a mass of 7 kg and is driven with S.H.M. that can be referred to a vector of length 60 mm rotating at 24 rad/s. The valve works in oil which creates a viscous resistance proportional to the velocity at the rate of 10 N/(m/s). Events controlled by the valve occur when it is 30 mm from its mid-position and moving towards it and, again, when it is 20 mm beyond its mid-position on the same stroke. Determine the time between these events. Evaluate the viscous resisting force at the first event and the force in the driving rod at the second.
