In this case, the forcing frequency is much lower than the natural frequency of the system and the magnification factor is nearly equal to unity i.e., the dynamic response is almost same as static response. In other words, since the forcing frequency is so slow, the system responds almost as if the load were static. Thus the response in this regime is governed by the stiffness of the system.

For , the dynamic magnification factor equals 1.125 i.e., the dynamic response is just about 12.5% more than the static response. In such cases, one needs to critically assess whether it is indeed necessary to perform a full fledged dynamic analysis or it is sufficient to just perform a simple static analysis with the knowledge that the actual response could be slightly higher.
