You are able to hold your arm in an outstretched position
because of the deltoid muscle. The force diagram for this is shown
below. Assume that the weight of the humerus is 8 lb (with a center
of gravity as shown), and that the deltoid muscle makes an angle of
α = 18 degrees to the humerus.
What is the magnitude of the tension in the deltoid muscle? What
is the magnitude of the force F at the joint?

You are able to hold out your arm in an outstretched horizontal position because of the action of the deltoid muscle. Assume the humerus bone has a mass M1=3.6kg, length L=0.66m and its center of mass is a distance L1=0.33m from the scapula. (For this problem ignore the rest of the arm.) The deltoid muscle attaches to the humerus a distance L2=0.15m from the scapula. The deltoid muscle makes an angle of ?=17? with the horizontal, as shown. (Figure 1)...

Deltoid muscle Fig. 1a Problem #2.1 You are able to hold your arm in an outstretched position because of the deltoid muscle. The force diagram for this is shown in Fig. 1b. Use the equilibrium conditions to determine the tension T in the deltoid muscle needed to achieve this equilibrium, and the vertical and horizontal components of the force exerted by the scapula (shoulder blade)on the humerus. Assume the weight of the humerus is 36.0 N and the deltoid muscle...

Exercise 11.22
You are doing exercises on a Nautilus machine in a gym to strengthen your deltoid (shoulder) muscles. Your arms are raised vertically and can pivot around the shoulderjoint, and you grasp the cable of the machine in your hand 64.0 cm from your shoulder joint. The deltoid muscle is attached to the humerus 15.0 cm from the shoulderjoint and makes a 12.0 degrees angle with that bone. (See the figure below.)http://tinypic.com/view.php?pic=jfx1z7&s=5A)If you have set the tension in the cable of...

When you hold your arm outstretched, it's supported primarily by the deltoid muscle.
When you hold your arm outstretched, it's supported primarily by the deltoid muscle. The given figure shows a case in which the deltoid exerts a 67 N force at 15 degrees to the horizontal. If the force-application point is 18 cm horizontally from the shoulder joint, what torque does the deltoid exert about the shoulder?
