Considering the free vibration response of a single degree of freedom system: It is observed ,that, larger the Time Period (Vibration Period -"T") of the system(consider a single degree of freedom system), greater is the peak deformation of the system.Right? Time Period on the other hand is directly proportional to the mass (m)(T=2*pi*sqrt(m/k)) , k being the stffness of the system. This means a system having more mass hence more "T" will have higher peak deformation.Right? But if a system has more mass it offers more inertia, right?Now, if the system offers more inertia should'nt the peak deformation be less?? Plz. help!!!
