        They dont vary over time.They allways affect the structure in the same way.
- - - - If the material or shape of the structure is not appropiate, stresses can cause it to break. If a structure is resistant, it can support or 'resist' the stresses.
        
        There are 3 types of stresses
        
        ᴛʀᴀᴄᴛɪᴏɴ
        
        Forces try to strech the object they are acting upon. Opposing forces move outwards away from the body along the same trayectory but in opposite directions. The body tens to become longer.
        
        𝐁𝐞𝐧𝐝𝐢𝐧𝐠
        
        Forces try to bend a body. This stress act on elements that are supported at their extremities and have weigh applied on them. Normally there are two forces that are separated by a certain distance and a third force acting in the opposite direction.
        
        COMPRESSION
        
        Forces try to flatten
        or compress a body. Opposing forces to move inwards towards one another along the same trajectory and in opposite directions. The body tends to lose its shape and becomes compressed.
        
        TORSION
        
        Forces try to twist a body. They try to turn the ends of the body in opposite directions.
