Four types of internal forces are tension, torsion, gravity, and compression true or flase
Answers
Answer:
There are four main types of internal forces acting upon suspension bridges; tension, compression, torsion and shear. Tension: Tension is the pulling force that acts on the cables and suspenders of a suspension bridge. Think about pulling an elastic band, you are able to see that a force is acting on the band as you pull it. This is tension.
Compression: Compression is a pressing force that acts on the towers of a suspension bridge as they are acted upon by gravity. Think about springs, as you compress a spring it becomes smaller and the particles get closer together. This is similar as to what force is being exerted on the bridge.
Torsion: Torsion is a twisting force that can be seen when suspension bridges are put under high wind speeds. The bridge will begin to move and twist if torsion is not taken into consideration. An example of torsion could be wringing a cloth.
Shear: Shear forces occur when forces push or pull in opposite directions. This can cause an object to bend or break. An example of shear force can be a tree that is planted to the ground being hit with a strong gust of wind horizontally. This will cause the tree to break. In a suspension bridge the towers and cables can experience opposite forces (cable pulling left/right while towers compress down) and if this is not taken into account for, the bridge will completely bend and break.
