Contribution to the Scottish Diaspora Tapestry Tour
The September 2016 Scarborough Exhibition of the 305-panel Scottish Diaspora Tapestry was definitely unique. In the Thomas Telford Engineering Challenge, senior high school student teams were invited to design a thirty-six-foot long model of the central unsupported span of the Menai Suspension Bridge by which the entire Tapestry could (theoretically!) be hung at the Scarborough Exhibition. The Menai bridge – arguably the world’s first modern suspension bridge -- was designed by Scottish civil engineer Thomas Telford (ca 1820). Telford had apprenticed as a stone mason in Dumfriesshire, Scotland, alongside the Thomson brothers who later settled in Scarborough. The Thomas Telford Engineering Challenge will get students to practise the kinds of thinking that Telford probably used in order to “come up with this new kind” of longer-span bridge. Following his presentation at the Education Conference of Professional Engineers Ontario this past May (2016), an article about this design challenge was written by a grade 12 Scarborough student from SATEC@W.A.Porter CI.
