Biomechanical forces [Mechanical engineering]

Biomechanical forces


There many types of forces to consider when looking at biomechanics. A detailed consideration of these forces is necessary to achieve a full picture of the biomechanical system. There are 4 types of forces to consider with biomechanics mentioned below. However, this is by no means an exhaustive list of all the forces involved with biomechanics. It is only meant to display the amount of complexity involved with human biomechanics and to help compose a free-body diagram.

  • Motion Forces -Rotatory, Tranlatory, Curvilinear
  • External Forces – Gravity, Wind, Objects, Other People
  • Internal Forces – Muscles, Connective Tissue (Elastic), Bone
  • Reactionary Forces – Ground Reaction, Joint Reaction, Gliding/Shear/Friction

Force is the basic component that biomechanics are built upon. Force is a vector component that has a point of application, a magnitude, and a direction. There are many types of forces that act on a biomechanical system. Being able to construct a detailed free-body diagram of the primary segment and adjacent segments will help to develop the full static and/or dynamic biomechanical picture.

The main reason I do this blog is to share knowledge and to help people become better clinicians/coaches. I want our profession to grow and for our patients to have better outcomes. Regardless of your specific title (PT, Chiro, Trainer, Coach, etc.), we all have the same goal of trying to empower people to fix their problems through movement. I hope the content of this website helps you in doing so.

If you enjoyed it and found it helpful, please share it with your peers. And if you are feeling generous, please make a donation to help me run this website. Any amount you can afford is greatly appreciated.
