摘要：

This paper analyses a particular structural assembly that has two independent inextensional mechanisms and two independent states of self-stress. It is shown that, for certain values of a variable bar length, this assembly is a first-order infinitesimal mechanism, and yet it cannot be stiffened by the imposition of a state of prestress.
