The Iron Cross When a gymnast weighing 750 N executes the iron cross as in Figure lN.91a, the primary muscles involved in supporting this position are the latissimus dorsi (lats") and the pectoralis major (pecs"). The rings exert an upward force on the aims and support the weight of the gymnast. The force exerted by the shoulder joint on the arm is labeled Fs, while the two muscles exert a total force Fw on the arm. Estimate the magnitude of the force Fw. Note that one ring supports half the weight of the gymnast, which is 375 N as indicated in Figure P8.91b. Assume that the force Fw acts at an angle of 45 below the horizontal at a distance of 4.0 cm from the shoulder joint In your estimate, take the distance from the shoulder joint to the hand to be L = 70 cm and ignore the weight of the arm.

A cat walks along a plank with mass M = 6.00 kg. The plank is supported by two sawhorses. The center of mass of theplank is a distance d1 = 0.850 m to the left of sawhorse B. When the cat is a distance d2 = 1.11 m to the right of sawhorseB, the plank just begins to tip. What is the mass of the cat, m?
A large airplane typically has three sets of wheels: one at the front and two farther back, one on each side under the wings. Consider the Boeing 787 "Dreamliner", with a mass of 198000 kg. In this particular model, the distance from the front wheels to the rear set of wheels is 23.8 m. a) If the center of mass of the airplane is along a line through the center and 3.00 m in front of the rear wheels, how much force, in meganewtons, does the ground exert on each set of rear wheels when the plane is at rest on the runway? b) How much force, in meganewtons, does the ground exert on the front set of wheels?
Jane carries a heavy object in two different body positions. If the weight of the object (Fp) is 250N, and the weight of her upper body (Fw) is 500N. In scenario A, she has an upright posture.
