What forces affect bridges?
Torsion, compression, and tension
What are the five forces that act upon bridges?
1.compression 2.tension 3.torsion 4.shear 5.gravity
What are the stresses on bridges?
There are a number of stresses inflicted upon bridges. Some of these stresses include compression, tension, as well as bending.
Why do you have truss bridges?
Truss bridges are lighter than beam girder bridges. They take up more height but are strong and carry loadd in tension and compression rather than bending.
What forces act upon arch bridges?
Tension and compression are the two forces that act upon a bridge.
Why are Arch bridges made of stone?
It's all about compression and tension. Compression is the force pushing in on an object. If you sit in a chair your weight is a compressive force on the chair. Tension is the force pulling on an object. If you hang from a rope your weight puts the rope in tension. Stone is very strong under compression but can break easily under tension. An arch bridge only has compression forces within it so stone is a good material for an arch bridge.
How do compression and tension create motion?
tension streches it compression squeezes it
What is rock deformation?
it is the movement of tectonic plates due to compression and tension which causes rock to fold and deform
What stress causes earthquakes?
There are three types of stress tension, compression, and shearing they all cause earthquakes.
What is the type of stress for a reverse fault?
In a reverse fault the maximum principal stress is horizontal, compression causes reverse (thrust) faults.
Compare the way that compression affects the crust to the way that tension affects the crust?
compression and tension are opposite. compression pushes the crust together but tension pulls it apart
Why was the crack an effect of tension and not compression stress?
A crack is caused by tension not compression because tension pulls matter apart while compression pushes matter together
