Taper suspension bridge Taper suspension bridge The taper suspension bridge (also known as the taper principle) is a bridge design patented by James Dredge in 1836. On a conventional suspension bridge the whole deck is suspended on vertical cables, rods or chains from a single cable or chain slung between two supporting towers. The taper suspension bridge that James Dredge devised in the early nineteenth century differs from the conventional suspension bridge design in that it is, in effect, a double cantilever bridge. Each of the opposing cantilever systems are self-supporting. The cantilever half-deck structure of each cantilever is suspended on angled chains
Pontoon (card game) D9 = doubling on 9–11 only) As all Australian casino Blackjack games have house edges greater than 0.5%, Pontoon is the superior of the two games. In general, casino staff and Blackjack players erroneously believe that Pontoon has a higher house edge than Blackjack, because the removal of the ten-spot cards creates a 2% disadvantage for the player. In Pontoon, the player can draw to "21" and win against a dealer Blackjack; this combined with "not-last-chance" doubling, forfeit, player "21" always wins, player Blackjacks always get paid at 3:2, and bonuses on certain hands, actually "overcompensates" for the 2% disadvantage.
