A truss is a structure consisting of straight members
connected at their extremities only. The members being
slender and unable to support lateral loads, all the loads must
be applied at the joints; a truss may thus be assumed to
consist of pins and two-force members.

There have been a number of different London Bridges over the past 2000 years. The one to which the nursery rhyme refers is the one started by engineer John Rennie in 1825 and finished in 1831. The design was superior, containing only five high arches, and constructed from strong Dartmoor granite. It was opened by King William the fourth in 1831. When it became necessary to widen the bridge some 70 years later, this process weakened the bridge's foundations to the point where it began sinking an inch every eight years. In 1968, it was auctioned and sold for $2,460,000 to Robert McCulloch who moved it to Havasu City, Arizona, where it was rebuilt brick by brick, and finally opened and dedicated on 10 October 1971.

It's the Mycenaen Arkadiko in Greece, built in 1300 B.C. It has a tiny arch in its middle. A more impressive but more recently built bridge is the Ponte Fabricio in Rome. It was built in 62 B.C.

Aquaphobia i think
Other Person: I have this phobia and Aquaphobia can also be called Hydrophobia which is also known as the fear of being in large bodies of water. Although some people (like me) can still drink and take regular showers in water.

How about a pimple that is under the skin . Actually a build up of bacteria . Often it's an ingrown hair. If your Ph level is off you can get a very sore little bump inside the nostril, in your mouth on your tongue, sore gums or even a sore on your lip. In a day or so the bump will go away. Most people get them.

Bridges and tunnels help carry transport, goods and people. This also shortens the amount of time to travel from a place to another. They also both have different types of bridges and tunnels e.g. bridges- suspension bridge, cable-stayed bridge, beam bridge, rope bridge, swing bridge, arch bridge e.t.c. tunnels- road tunnels, high tunnels, wind tunnels, network tunnels e.t.c.
Every time you want to cross a bridge or tunnel you have to pay a toll to get through.

In this short story Ernest Hemingway uses a lot of metaphors and symbols. One of the symbols is the bridge, which represents uncertainty and dangers. Those are the feelings most of the people have during wartime. In contrast to this stands the fact that the story takes place on Easter Sunday, a holiday that stands for hope and the faith in God. The feelings of the refugees probably stand in the same contrast. On the one hand they feel very frightened and worried, but on the other hand they do not want to lose hope. The animals also stand for different qualities. The pigeons, for example, represent peace and harmony and the fact that they fly away, away from the war, maybe is a reference to the refugees who flee from the war to a safer place. The cat, being a symbol of independence, does not need anybody to survive, but the goat is often used as a sacrificial animal and this probably represents the old man and his situation. Like a goat which is sacrificed, the old man's fate is sealed.

Think of it this way, unquestionably the strongest structure is a solid.
But now the compromises begin: Is weight a factor? Is material cost a factor? Does it need to be hollow?
Once these parameters are known, then the loads must be determined. Are the loads static, dynamic, vibratory, etc. Are the loads in shear, torsional, moment, cantilever, etc. Do we need to consider earthquake, thermal loads, or impact loads?
And we must look at the desired building material(s):
steel has the same strength in all directions (isotropic, wood, concrete, and composites are wildly non-isotropic
so the direction of the loads becomes important.
Take the case of a sky scraper. We must consider the shape of the occupied area as well as all the necessary load cases. Thus we end up with a square girder structure which is not the strongest perhaps, but is adequate and meets all the other requirements.
Considering bridges, for short spans the basic AASHTO
concrete girder and deck is extremely durable and strong as well as cost effective. For longer spans we look at arcs of structural steel which are extremely strong and beautiful, or cable suspension/cable stayed designs using concrete piers that can withstand hurricane force winds.
The Eiffel Tower was built for the International Exhibition of Paris in 1889, but despite the age, it remains one of the worlds most brilliant examples of construction.
Some key observations:
1. Notice that it is open, the structural elements are exposed. This reduces wind loads (routinely 100 MPH at the top!) and saves cost.
2. Notice the arches combined with the "X" structural shapes. Arches are very efficient material wise, the "X" prevents buckling.
3. Notice the width at the base. This is an amazingly stable and
strong structure.
4. Steel (actually puddled or wrought iron in this case) members can be rapidly assembled. This required 300 workers for two years. A bargain!
5. Super lightweight: it has been said that a 1 foot high scale model would only weigh as much as a nickel!
