I spent the 1972-73 academic year on sabbatical leave at the Kingston, Jamaica, campus of the University of the West Indies. One of my duties was to give Saturday morning enrichment lectures to the students, and the best one was on suspension bridges. The demonstration lecture then went on tour to high schools in Jamaica and the Cayman Islands. During the course of the talk, I "built" the suspension bridge in Fig. 1; this picture was published in the January 1974 issue of "The Physics Teacher."
