Biomechanics problem. Have no idea

In summary, biomechanics is the study of the mechanical principles of living organisms, combining biology, anatomy, physics, and engineering to understand how the body moves and functions. It is used to address common problems such as injury prevention, rehabilitation, and performance enhancement in sports, as well as to study bone and joint diseases and design medical devices. In sports, biomechanics is utilized to analyze and improve athletic performance, prevent injuries, and design better equipment. Tools and techniques such as motion capture systems, force plates, and computer simulations are used in biomechanics research. Career options in this field include roles in academia, industry, sports performance, medical device design, and rehabilitation. Some individuals also pursue careers in physical therapy or athletic training.

Shoulder abduction = 15°
Abduction acceleration = 50/rad/s/s
Abduction velocity = 20 rad/s
Radius of gyration and COM location from joint = 25cm
Mass of hand + Arm = 8 kg
Force of middle deltoid =400N
Middle deltoid only active muscle
Force of theraband = 70N
Middle deltoid insertion = 15°
Φ=90

The question is: solve for joint reaction force compression on the bone.

You need to show some attempt. Start with a free body diagram.
Also, most readers on this forum won't know all these technical anatomy terms. An abstract force diagram will help us.
 

FAQ: Biomechanics problem. Have no idea

1. What is biomechanics?

Biomechanics is the study of the mechanical principles of living organisms, particularly humans. It combines the fields of biology, anatomy, physics, and engineering to understand how the body moves and functions.
