The figure below shows a simplified model of the arm. Draw the forces acting on the forearm. Assume that the biceps connects to the forearm perpendicularly so that all the force it exerts is in the vertical direction.

Draw the vectors starting from the point of application of each force. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.

There is an image on the canvas: Two rods are connected by a ball joint. One rod extends vertically upward from the joint. The other rod extends horizontally rightward from the joint and has length d subscript ball. Distance d subscript biceps is measured from the left end of the horizontal rod to some point on the rod. Distance d subscript biceps accounts for a bit over one third of d subscript ball.
