Q2-A man is holding a 3.6-kg sphere in his hand with the entire arm held horizontally as shownin the figure. tensile force in the deltoid muscle prevents the arm from rotating about theshoulder joint O; this force acts at the angle shown. Determine the force exerted by thedeltoid muscle on the upper am at A and the x- and y-components of the force reaction atthe shoulder joint O. The mass of the upper arm is (m,-1.9 kg), the mass of the lower arm is(m-1.1 kg), and the mass of the hand is (mg-0.4 kg); all the corresponding weights act atthe locations shown in the figure.Group AX=2 mmGroup BX= 4mmmGroup Cy3.6(9.81) NDeltoid muscleFD21°Wy125 mmWLWH130 mm412 mm(635+x) mm

BIO When a gymnast performing on the rings executes the iron cross, he maintains the position at rest shown in Figure P10.85a. In this maneuver, the gymnasts feet (not shown) are off the floor. The primary muscles involved in supporting this position are the latissimus dorsi (lats) and the pectoralis major (pecs). One of the rings exerts an upward fore Fh on a hand as shown in Figure P10.85b. The force Fs is exerted by the shoulder joint on the arm. The latissimus dorsi and pectoralis major muscles exert a total force Fm on the arm. (a) Using the information in the figure, find the magnitude of the force Fm. (b) Suppose an athlete in training cannot perform the iron cross but can hold a position similar to the figure in which the arms make a 45 angle with the horizontal rather than being horizontal. Why is this position easier for the athlete? Figure P10.85
