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 15 kg monkey climbs a uniform ladder with weight 1.2 *10^2 N and length L=3.00 m. The ladder rests against the wall and makes an angle of theta= 60.0 degrees with the ground. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope. HInt : Draw a force diagram for the ladder and the normal forces from the ground and wall acting on the ladder. A) find the tension in the rope when the monkey is two-thirds of the way up the ladder. B) The rope is frayed and can support a maximum tension of only 80N. Find the maximum distance that the monkey can climb up the ladder before the rope breaks. C) If the horizontal surface were rough and the rope were removed, how would your analysis of the problem change? What other information would you need to answer parts (a) and (b)
