Consider the damped mass-spring system for mass of 0.1 kg, spring constant 8.5 N/m, damping 0.38 kg/s and an oscillating force 3.5 cos(wt) Newtons. That is, 0.1" +0.38x' + 8.5x = 3.5 cos(wt). What positive angular frequency w leads to maximum practical resonance? 3 9.21 help (numbers) What is the maximum displacement of the mass in the steady state solution when the we are at practical resonance: 3.5 help (numbers) C(w)= (8.5-0.12)+(0.381) 2
