Why are the forces exerted on the outside world by the limbs of our bodies usually much smaller than the forces exerted by muscles inside the body?
Under what conditions can a rotating body be in equilibrium? Give an example.
Suppose just two external forces act on a stationary, rigid object and the two forces are equal in magnitude and opposite in direction. Under what condition does the object start to rotate?
BIO The arm in Figure P10.35 weighs 41.5 N. The gravitational force on the arm acts through point A. Determine the magnitudes of the tension force F1 in the deltoid muscle and the force Fs exerted by the shoulder on the humerus (upper-arm bone) to hold the arm in the position shown. Figure P10.35
Based on the illustration,what must be true of all these force for the body to be in equilibrium?
The figure below shows a human arm that weighs 41.10 N. The arm is extended outward and is motionless. The gravitational force Fg on the arm acts at point A, a distance of 0.2900 m from the shoulder joint, which is represented by point O. The shoulder pushes down and to the right on the humerus bone of the arm with a force Fs at point O, at an angle ? as shown. The deltoid muscle pulls back on the arm toward the shoulder with a tension force Ft. This tension force acts at a point 0.08000 m to the right of point O, and it is directed up and to the left, at a 12.00° angle with respect to the horizontal. An arm is extending horizontally to the right with a cutout that shows muscles in the upper arm. A horizontal dashed line extends along the bottom of the muscles and another along the top. Point O is labeled at the left end of the arm on the lower horizontal line. An unlabeled point lies 0.080 m horizontally to the right of point O. Point A lies 0.290 m horizontally to the right of point…
An athlete holds a 7.5-kg shot put in his hand with his lower arm horizontal, as shown in thefigure. His lower arm has a mass of 2.8 kg and its center of gravity (or center of mass) is 12 cmfrom the elbow-joint pivot. How much force must the extensor muscle (which is FM in thefigure) in the upper arm exert on the lower arm? Choices: 500 N 2000 N 1500 N 2500 N 1000 N Show complete solution and free body diagram
During a circus act, one performer swings upside down hanging from a trapeze holding another, also upsidedown, performer by the legs. If the upward force on the lower performer is three times her weight, how much do the bones (the femurs) in her upper legs stretch? You may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. Her mass is 60.0 kg.
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?
The wheelbase of a pickup truck is 3.00 m. In ordinary cases, 10,780 N rests on the front wheels and 8820 N on thewheels when the truck is parked on a level road. A box weiging 3500 N is now placed on the tailgate, 1.00 m behind therear axle. (a) How much total weight now rests on the front wheels? (b) On the rear wheels?
A jet transport has a weight of 1.71 × 106 N and is at rest on the runway. The two rear wheels are 17.0 m behind the front wheel, and the plane's center of gravity is 10.6 m behind the front wheel. Determine the normal force exerted by the ground on (a) the front wheel and on (b) each of the two rear wheels.
You hold a softball with a weight of 1.80 N in your hand as shown in the figure. Your arm is moving, but at the instant shown, your arm is horizontal. Consider your forearm and hand to be a uniform rod with a mass of 1.65 kg and the distance between your elbow joint and the ball in your hand is 2L = 26.0 cm. Your biceps exerts an upward, vertical force of 13.5 N on your forearm and is attached a distance of d = 2.60 cm from your elbow. (a) Using your elbow joint as the axis of rotation, determine the magnitude of the net torque acting about your elbow due to the weight of your forearm/hand, the weight of the ball, and the force applied by your bicep.
