What is the weakness of a suspension bridge?
The strengths of Truss bridges are that Truss bridges can support and resist lateral loads. Another is that unlike the Arch and Beam bridges, the Truss bridge prevents twisting and swaying during earthquakes and high winds. Truss bridges also resist the forces of compression and tension.
Are scissors wedges?
No, scissors are not Wedges. They are complex levers, consisting of 2 applied forces, one fulcrum, and 2 loads.
What are the forces acting on landing gear during landing?
vertical loads, longitudinal loads and vertical loads
Are scissor a wedge?
No, scissors are not Wedges. They are complex levers, consisting of 2 applied forces, one fulcrum, and 2 loads.
What is the actual job of a structural engineer?
The job of a structural engineer is to deal with the analysis and design of the structurre. They choose the materials that must support the loads and resist tension and compression. The structure must be able to withstand the forces, weather and some natural disasters.

Which bridge design is most earthquake resistant?
There are many factors to consider in this question and many types of bridge structure. The structure of a bridge is designed to resist the expected loads that will act on it. The main loads that usually act on a bridge are: - gravity (an acceleration downwards towards the centre of the Earth) on the bridge itself, - gravity on any objects on the bridge, - wind loads on the bridge ( can be in any direction but depends on exposure) - earthquake loads The loads experienced by the bridge in an earthquake can be as strong as or stronger than gravity (9.8ms-2), and act in many directions changing rapidly. A bridge designed to resist these therefore needs to have a structure that can resist significant forces in many directions, (to picture these forces it may help to imagine a model of the bridge being tossed from hand to hand, twisted and shaken), or it can be isolated from the earthquake forces by allowing the earth to move up down and around while the bridge sits quietly. If we look at the example of a simple suspension bridge for one person to walk over, made from some steel cables and wire mesh: - it is light and will not need to resist huge forces (Force= mass.acceleration), - it has the advantage of the elasticity of the steel, - it has the disadvantage that if it is not under much tension ( ie. has slack cables), these may be snapped rapidly in different directions in an earthquake, (picture a whip being used) which will put big loads on them.
What innovation or invention made suspension bridges possible?
Suspension bridges are one of the oldest engineering forms, dating back to the 4th century. Modern suspension bridges were made possible by the web truss, invented by John Augustus Roebling. The web truss made a very sturdy, rigid structure that could withstand storms, wind forces, and heavy loads.

What is factored load and Service load?
Basically, service loads are those applied loads which have not yet been factored. Also known as "working loads"
What is a Dynamic loads?
any load which is nostatic, such as wind load or moving lie load
