Hardy Cross is no longer with us, but engineers these days think of him when they come across his contribution to the explanation of bending moments in structural frames and flow in networks. At times he is even brushed off as a somnambulist who tripped on the relaxation method for solving linear simultaneous equations. Cross’s power on the work of structural engineering is ineffaceable and overwhelming. At the same time, it is too delicate and trouble-free to ignore. And to me, Cross’s writings in black and white are furnished with jewels of ideas which hold good even today.
