Forth Rail Bridge
The 2.5 km. (1.5 mile) Forth Railway Bridge, the world’s first major steel bridge, with its gigantic girder spans of 521 m. (1710 ft.) ranks as one of the great feats of civilization. It was begun in 1883 and formally completed on 4 March 1890 when HRH Edward Prince of Wales tapped into place a ‘golden’ rivet. Tancred–Arrol, constructed the bridge, robustly designed in the aftermath of the Tay Bridge disaster by civil engineers Sir John Fowler and Benjamin Baker. The balanced cantilever principle was adopted. The main crossing comprises tubular struts and lattice-girder ties in three double-cantilevers each connected by 105 m. (345 ft.) ‘suspended’ girder spans resting on the cantilever ends and secured by man-sized pins. The outside double-cantilever shoreward ends carry weights of about 1000 tonnes to counter-balance half the weight of the suspended span and live load. This concept is readily understood from Baker’s ‘human cantilever’ model with his assistant Kaichi Watanabe representing the live load. The pull in his supporters arms indicates the tension in the ties and the push in the lower struts the compression in the tubes. Each of the 110 m. (361 ft.) high double-cantilevers is supported on well-founded granite faced piers. The bridge’s construction involved the employment of 4,000 men at times, the use of 54,000 tonnes of steel and driving 6,500,000 rivets. Its total cost was £3,200,000 (~£235,000,000 today).

Cute, good quality, *****!
Exactly as expected!
My order was delivered very quickly and was high quality. Glad to add it to my mug shelf.
God is still alive. The existence of this mug shows there is still faith that god is dead and is listening to us. God Bless,
Gay Label Adore this. Ordered for my husband, with the second definition on the back, about the gay filmmaker. Makes a nice discussion starter.
Top notch shipping and exactly what I hoped!!
Best mug i have ever purchased! Subscribe
I love it, but of course the definition Ichose for “Unicorn” is too long and gets cut off after “someone is remarkably attractive.” Is there any way to purchase a second mug that has the rest of the quote on it? They’d make a great set as a present. Please let me know. David Tillinghast dtilling480@gmail.com
