The figure below shows an image of an arm supporting a physics textbook. The mass of the book is 4 kg and is located 38 cm from the elbow joint. The mass of the forearm is 2.5 kg and the center of gravity of the forearm is taken to be 16 cm from the elbow joint. To hold the book level, the bicep muscles exert a force located 4 cm from the elbow joint. Screenshot 2025-06-25 at 1.38.34 PM.png a.
