Combining a pin movement with a suspension bridge would
create a draw bridge effect at one of the towers
|
Combining a pin movement with a cable stayed bridge would
create the same type of draw bridge as in the suspension bridge
|
Combining a pin movement with an arch bridge would be
more difficult due to the fact that there is not a tower to pull the
draw section
|
|
|
Adding a
pulley system to a suspension bridge would require additional
cables and devices to allow the deck to move or lift
|
The same results as a suspension bridge would occur
when adding a pulley system to a cable stayed bridge
|
A pulley system would work best with an arch bridge because
the vertical cables are ideal for lifting the desired portion of the
deck
Easiest Design

|
A slide movement on a suspension bridge would
require the removal of several cable which could compromise the deck
|
The cable stayed bridge is better equipped to carry
a sliding movement because one of the towers could be removed while the
size of the other is increased to compensate for the increased load of
the deck
|
An arch bridge would be difficult to combine with a sliding
movement because the principles that give the arch its strength must be
removed make the arch itself useless
