Question

Consider an SDOF system of mass m, stiffness k, and damping coefficient c. Now if the mass of the system increases 4 times, what will be the change in the damping ratio?

no changes

become half

increases by 2 times

increases by 4 times

Answer 1

Consider an SDOF system of mass m, stiffness k, and damping coefficient c. Now if the mass of the system increases 4 times then damping ration will become half.

so the answer b) become half will be accurate
