Forces
Briefly explain what impact the following forces may impact upon a structure:
Compression (squeezing)- compression is a force that squeezes the material together. When a material is in a compression it tends to become shorter.
Tension (stretching)- Tension is force that stretches material apart. When a material is in tension, it tends to become longer.
Bending- When a straight material come curved, one side squeezes together and the other side stretches apart. This action is called bending.
Shear (sliding)- Shear is a force that causes parts of a material to slide past one another is the opposite directions.
Torsion (twisting)- Torsion is an action that twists a material.
