The amount of torque which must by generated by the biceps brachii at the elbow in order to maintain the arm in a particular position is 50 Nm. If the biceps attaches to the radius at a perpendicular distance of 3 cm from the joint center at the elbow,how much force must the muscle produce?

Question

To find the force produced by the biceps, use the torque formula: Torque = Force x Distance. Rearrange to solve for Force: Force = Torque / Distance. Convert distance to meters: 3 cm = 0.03 m. Substitute the given values: Force = 50 Nm / 0.03 m = 1666.67 N, which rounds to 1667 N.
