The chewing muscle, the masseter, is one of the strongest in the human body. It is attached to the mandible (lower jawbone). The jawbone is pivoted about a socket just in front of the auditory canal. The forces acting on the jawbone are equivalent to those acting on the curved bar as shown in the figure. ?C is the force exerted against the jawbone by the food being chewed, ?T is the tension in the masseter, and ?R is the force exerted on the mandible by the socket. Find (a) ?T and (b) ?R if you bite down on a piece of steak with a force of 50.6 N. Neglect the weight of the jawbone. (a)T. (b)R.

The board sandwiched between two other boards in Figure P4.91 weighs 95.5 N. If the coefficient of friction between the boards is 0.663, what must be the magnitude of the compression forces (assumed to be horizontal) acting on both sides of the center board to keep it from slipping? Figure P4.91
The figure below shows a bird feeder that weighs 158.9 N. The feeder is supported by a vertical cable, which is in turn tied to two cables, each of which is attached to a horizontal post. The left cable makes a 60° angle with the post, while the right cable makes a 30° angle. What is the tension in each cable (in N)? left cable N Right cable N bottom cable N
If you hold your arm outstretched with palm upward, as shown, the force to keep your arm from falling comes from your deltoid muscle. The arm of a typical person has mass 4.0 kg and the distances and angles shown in the figure.a. What force must the deltoid muscle provide to keep the arm in this position?b. By what factor does this force exceed the weight of the arm?

When a gymnast weighing 740 N executes the iron cross as in figure (a), 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 arms 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 Fm on the arm. Determine the magnitude of the force Fm. Note that one ring supports half the weight of the gymnast, which is w = 370 N as indicated in figure (b). Assume that the force Fm 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 = 71 cm and ignore the weight of the arm.
As shown on the right, a uniform rod with a weight W= 100 N and a length L = 2.0 m is hinged at the bottom end and is vertical. A light cable, tied to the rod at a height of h = 1.0 m, makes an angle 0 = 40° from the horizontal. A horizontal force F= 50 N is exerted at a height H = 1.5 m on the rod. (a) Draw a free-body diagram for the rod.(b) What is the tension in the cable?(c) What are horizontal and vertical components ofthe force exerted on the rod at the hinge?

A horizontal beam of length 4.08m and weight 130N is attached to a vertical wall at a right angle. There is also a support wire of length 5.04m which attaches the far end of the beam to the wall from above. Off of the far end of the beam also hangs an object of weight 330 N.

(c) What is the vertical component of the force exerted on the beam at the wall?
The two blocks (m = 13 kg and M = 90 kg) in the figure are not attached to each other. The coefficient of static friction between the blocks is μs = 0.44, but the surface beneath the larger block is frictionless. What is the minimum magnitude of the horizontal force F required to keep the smaller block from slipping down the larger block?
Some insects can walk below a thin rod (such as a twig) by hanging from it. Suppose that such an insect has mass m and hangs from a horizontal rod with angle u = 40. Its six legs are all under the same tension, and the leg sections nearest the body are horizontal. (a) What is the ratio of the tension in each tibia (forepart of a leg) to the insect’s weight? (b) If the insect straightens out its legs somewhat, does the tension in each tibia increase, decrease, or stay the same?
