They will create a model which is similar to that of the dimensions of the prototype. And also the model which is created should hsve same material properties of that of the prototype. And the model can be tested in the laboratory.
civil engineers, structural engineers, and architects are the main bridge builders.
They usually try to make the car they are designing, more fuel efficient, safer, and try to come up with ways to improve the current design.
All materials expand when heated and contract when cooled. Bridges are especially vulnerable because the entire bridge is surrounded by air, and it doesn't have the ground below to act as a heat sink. Without the expansion slots, the bridge would run the risk of buckling when heating, and pulling apart when cooling. This could damage a bridge. Uncontrolled or unsupported cracks, for example in the middle of a span could be very dangerous.
Becuase bending moment in the middle of the bridge bending moment is less than ordinary or straight bridge and more strength
Bridges get their name by the kind of bridge they are
Civil engineers and Structural engineers.
Civil Engineers and Architects design bridges and buildings.
bridges
To assist in removing obstacles and classifying bridges.
Engineers design things such as bridges or pipes based on scientific principles.
civil engineers, structural engineers, and architects are the main bridge builders.
Because bridges expand and contract with the change in temperature. The expansion joints allow the bridge to 'flex' as the temoerature rises and falls, ensuring the structure doesn't buckle or collapse.
Some websites that have pictures of bridge designs are: Highest Bridges, Garretts Bridges, Historic Bridges, Bridge Element, Design Bridge and Google Images.

Depends on the type of engineer. Originally, it meant one who cared for, and operated engines- like a railroad locomotive. While it still means that, there are other types of engineers. Civil engineers design roads, bridges, dams, and large buildings. Electrical engineers design electrical distribution and supply systems. Chemical engineers design chemical manufacturing processes. Military engineers may build bridges, destroy bridges, place or clear minefields, build obstacles, etc.
Different engineers do different things. Civil engineers may design dams, bridges, roads. Mechanical engineers design factories, production lines. Electrical engineers may design power systems, and chemical engineers design chemical manufacturing processes. Safety engineers design safe working procedures, and operating engineers operate boilers, locomotives, cranes, and large equipment. Aeronautical engineers design airplanes and spacecraft, and Marine engineers design ships. And there are others as well.
