Biomechanics | Elbow/Biceps Torque Problem #2

The video tutorial explores torque problems involving the elbow joint, focusing on calculating the force required by the biceps to hold a weight isometrically. It introduces additional variables, such as the weight of the forearm, and explains the process of solving the torque equation. The tutorial concludes with a discussion on the inefficiency of the bicep as a third-class lever and hints at future topics involving different angles and trigonometry.
