The board sandwiched between two other boards in Figure P5.97 weighs 95.5 N. If the coefficient of static friction between the boards is 0.663, what must be the magnitude of the compression forces (assumed horizontal) acting on both sides of the center board to keep it from slipping?
Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76
The leg and cast in Figure P4.40 weigh 220 N (w1). Determine the weight w2 and the angle needed so that no force is exerted on the hip joint by the leg plus the cast. Figure P4.40
Unlike mass, weight is not a(n) ___ property. (1.4)
This problem returns to the tightrope walker studied in Example 4.6, who created a tension of 3.94103 N in a wire making an angle 5.0° below the horizontal with each supporting pole. Calculate how much this tension stretches the steel wire if it was originally 15 m long and 0.50 cm in diameter.
Show that the acceleration of any object down an incline where friction behaves simply (that is, where fk=kN ) is a=g(sinkcos). Note that the acceleration is independent of mass and reduces to the expression found in the previous problem when friction becomes negligibly small (k=0).
Measuring coefficients of friction A coin is placed near one edge of a book lying on a table, and that edge of the book is lifted until the coin just slips down the incline as shown in Figure P4.82. The angle of the incline, C, called the critical angle, is measured. (a) Draw a free-body diagram for the coin when it is on the verge of slipping and identify all forces acting on it. Your free-body diagram should include a force of static friction acting up the incline. (b) Is the magnitude of the friction force equal to sn for angles less than C? Explain. What can you definitely say about the magnitude of the friction force for any angle c? (c) Show that the coefficient of static friction is given by s = tan c. (d) Once the coin starts to slide down the incline, the angle can be adjusted to a new value c c such that the coin moves down the incline with constant speed. How does observation enable you to obtain the coefficient of kinetic friction? Figure P4.82
Show that, as stated in the text, a force F exerted on a flexible medium at its center and perpendicular to its length (such as on the tightrope wire in Figure 4.17) gives rise to a tension of magnitude T=F2sin() .
A 6 kg rock is suspended by a massless string from one end of a 5m measuring stick what is the weight of the measuring stick if it is balanced by a support force at the 1m mark? the acceleration of gravity is 9.81 M/S2 Answer in units of N
A persons head is bent over a book. The head weighs P=37.2 N and is supported by the muscle force Fm exerted by the neck extensor muscles and by the contact force Fc excerted at the atlantooccipital joint. Given that the magnitude of Fm is 60.0 N and is directed 35.0 degree below the horizontal. Find the direction of the contact force Fc. If the direction is below the horizontal, enter a negative value.

During most of the stance phase of the gait, the knee flexion is less than 20º. What force must the quadriceps muscle apply to maintain this flexion while standing on one leg? The patient's weight is 836N, assuming that the distance from the center of the joint to the line of gravity is 5 cm and the distance perpendicular to the center of the joint towards which the muscle acts is 5 cm, and the muscle acts ( pull) at 60º to the horizontal.
