Biomechanics | Torque Problem #1b (Elbow Joint) [Calculate Joint Reaction Force]

The video tutorial explains the concept of joint reaction force in biomechanics, focusing on its calculation and significance in maintaining static equilibrium. It covers the process of calculating the joint reaction force due to the biceps brachii while holding a 40-pound ball in a 90-degree elbow flexion. The tutorial emphasizes the importance of balancing forces in both X and Y directions to prevent movement and maintain equilibrium. It also discusses the order of calculations, starting with torque to determine muscle force, followed by joint reaction force. The video concludes with a preview of future topics involving trigonometry in biomechanics.
