In an emergency situation,a person with a broken forearmties a strap from his hand to clipon his shoulder as in Figure P8.92.His 1.60-kg forearm remains in ahorizontal position and the strapmakes an angle of θ = 50.0° withthe horizontal. Assume the forearmis uniform, has a length ofl= 0.320 m, assume the bicepsmuscle is relaxed, and ignore themass and length of the hand. Find(a) the tension in the strap and(b) the components of the reactionforce exerted by the humeruson the forearm.
When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm is 1.10 kg . If the biceps is connected to the forearm a distance dbicepsdbicepsd_biceps = 2.50 cm from the elbow, how much force Fbiceps must the biceps exert to hold a 750 g ball at the end of the forearm at distance dball = 32.0 cm from the elbow, with the forearm parallel to the floor? Although it is uncommon, orthopedic surgeons have seen patients who have torn their biceps tendon when forces of greater than 390 N have been exerted on the tendon with the arm bent at the elbow so that the forearm is parallel to the ground. What is the minimum mass of a ball Mball such a patient might have held to cause the biceps tendon to tear?
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tree 15 m away, as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
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?

Consider the woman doing push-ups in the figure. She has a mass of 49.2 kg, and the distance from her feet to her center of mass is 0.96 m, while the distance from her feet to her hands is 1.75m. a. What force in newtons should the woman in the figure exert on the floor with each hand to do a push-up? Assume that she moves up at a constant speed. b. The triceps muscle at the back of her upper arm has an effective lever arm of 1.95 cm, and she exerts force on the floor at a horizontal distance of 15.5 cm from the elbow joint. Calculate the magnitude of the force in newtons for each triceps muscle. c. How much work in joules does she do if her center of mass rises 0.27 m? d. What is her useful power output, in watts, if she does 25 pushups in one minute? For the sake of simplicity, ignore any power used by her muscles lowering her body during each pushup.
