Before revision:  In this brief communication that work is extended to situations where the external forced is ramped up till the attachment gets ruptured . In spite of the fundamental differences in the underlying mechanisms, the trend of variation of the rupture force distribution observed in our model kinetochore-microtubule attachment with the increasing loading rate is qualitatively similar to that displayed by the catch bonds formed in some other ligand-receptor systems.
