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)...

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? Deltoid...
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?

when you hold your arm out horizontally it is supported by the deltoid muscle. In that position, the deltoid makes an angle of about 10 degrees from the horizontal and anchors to your arm about 6'' from your shoulder. Assume your arm weighs 8lbs and has a center of mass about 10'' from your shoulder. How much force does the deltoid need to exert in order to support your arm in this position. a. 77lbs b. 48lbs c. 13lbs

The arm in the figure below weighs 36.0 N. The force of gravity acting on the arm acts through point A. Determine the magnitudes of the tension force F, in the deltoid muscle and the force F exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. (Enter your answers to at least the nearest newton.) x Your response is within 10% of the correct value. This may be due to roundoff error,...
