John Roebling‚ the creative genius behind the Brooklyn Bridge project‚ had first envisioned it in 1852 after having witnessed the horrible delays caused by the East River choked with ice. However‚ because of suspicions among the public of whether a bridge that would have to be wide enough to allow boats to pass under it and strong enough to sustain the terrible winds and powerful currents of the river was possible‚ the project seemed unrealistic. The winter of 1866/1867‚ which was one of the worst

“The Old Man at the Bridge” by Ernest Hemingway An old man with steel rimmed spectacles and very dusty clothes sat by the side of the road. There was a pontoon bridge across the river and carts‚ trucks‚ and men‚ women and children were crossing it. The mule- drawn carts staggered up the steep bank from the bridge with soldiers helping push against the spokes of the wheels. The trucks ground up and away heading out of it all and the peasants plodded along in the ankle deep dust. But the old man

the project is to build a truss that would be able to take a specific amount of downward force remarkably with respect to the weight of the truss itself‚ i.e. to construct a truss that would hold a relatively high efficiency score. And construct the bridge in such a way to as to keep the deflection of the structure at minimal. Introduction First of all‚ what is a truss? In an engineering view‚ a truss is a structure that is made up of series of triangular unit made of straight members that are connected

Popsicle-Stick Bridge The goal: to build the strongest possible bridge to take a matchbox car‚ using wooden popsicle sticks. Constraints: The bridge must span a 55cm gap No more than 100 popsicle sticks may be used The sticks may not be cut Only white glue may be used Construction paper may be used for the deck only The test load is applied to a 4cm-wide section at the top of the arch. The test jig looks like this: (Well-built bridges can support over

Earthquake Resistant Bridges Jacqueline Stoy 4/24/2013 Geography of Cultural Diversity 3350:275 Tuesday/Thursday 12:05-12:55 Throughout history‚ bridges have been a primary means of transportation. Unfortunately‚ natural disasters have come to destroy such bridges on many occasions. One of the most deadly natural disasters to face the bridges is earthquakes. The movement of the ground causes the supporting beams and columns to twist and collapse‚ often resulting in injury or death for

the issues about how bridges collapse in just one glimpse. The first failure of a bridge happened August 29 by the year 1907‚ The Bridge was in Quebec and it killed 86 people. This is one of the most remarkable catastrophes in the field of Civil Engineering. Through this tragedy‚ aren’t the engineers and the people involved in construction never learned their lessons? And still record of failure of bridges still soar and one of the latest failures of a bridge was the India Bridge killing more than 45

Spaghetti Bridge Abstract For this assignment our task was to build as a group a spaghetti bridge with the objective of carrying the most weight as possible using only spaghetti and hot glue‚ meeting the specifications. The bridges will be loaded until they fall. After testing to destruction‚ the bridges loading capacity was 14.4kg‚ with an initial mas of 0.840kg. This gave a weight to strength ratio of 17.1 putting the group at 4th/8th position in class. From this it was learned the
