Question 31 2 pts In the schematic below, the deltoid muscle force (Force D) and the horizontal component of the glenohumeral joint reaction force (Force J) listed. Solve the following questions (below the schematic) based on the information provided below and assuming static equilibrium. Y+ Force D Force J' X+ 3 cm 30 cm .05 BW .025 BW 60 cm The sum of the moments around the shoulder is equal to The deltoid muscle forces required to balance the torques caused by the combined effects of the mass of the arm and the mass of ball held in the hand, is equal to . (answer only digits, no units, round to the nearest integer). The deltoid muscle force creates a moment that counteracts the moment caused the weight of the arm and ball, but causes a compressive force J, equal to the nearest integer). (answer only digits, no units, round to

Explain static equilibrium.
