Q3 A single degree of freedom system has a mass of mi, and a natural circular frequency of 23.6rad/s. If the value of damping coefficient was reduced to 10% of

the critical value, how long would i t take for an initial disturbance of n; mm from the position of static equilibrium of mass reduce to 2mm? • add all digits from your date of birth and divide by 4 to obtain A in metric tons,i.e. for 19/04/82 you would get A= (1+9+0+4+8+2)/4=6tn= 6000kg • n=m/200mmi.e., you have worked out your mass as 6000kg, you get 6000/200=30mm
