4. Draw complete, clearly labeled free-body diagrams. All unknown support reactions should be clearly labeled with a variable name. All known values such as weight or applied forces should be clearly labeled with their known values.

Don't need to show equilibrium equations, I just need free-body diagrams. Only solve this text question, not the questions in image.

A woman is holding a 2.8-kg sphere in her hand with the entire arm held horizontally as shown in the figure. A tensile force in the
deltoid muscle prevents the arm from rotating about the shoulder joint O; this force acts at the 23° angle shown. Determine the force
Fp exerted by the deltoid muscle on the upper arm at A and the x- and y-components of the force reaction at the shoulder joint O
(positive to the right and up). The mass of the upper arm is my= 2.0 kg, the mass of the lower arm is m₁= 1.0 kg, and the mass of the
hand is mH= 0.4 kg; all the corresponding weights act at the locations shown in the figure.
