Tensile force

• Tension - Tension is when something is in the state of being stretched or bent.
  
• Torsion - Torsion is a turning or twisting force.
  
• Stress and release - Stress and release is the relationship between applying a force and easing/lessening a force.
  
• Equilibrium - Equilibrium is a stable state. It is usually characterized by the cancellation of all forces by equal opposing forces. This can be similar to balance in that the forces are “balanced.”
