The tangential force F2 leads to shear stress and therefore is not con- sidered further order 100mg zoloft with mastercard anxiety techniques. The normal stress distribution from M buy cheap zoloft 25mg on-line anxiety 24 hour helpline, on the other hand generic zoloft 100 mg on line depression kidney disease, varies linearly as shown in Fig. To calculate the normal stress at a certain point in the cross section, one must add both contributions. In the ad- dition, tensile stress is considered positive, compressive stress negative. While she is climbing stairs, the high heel of a woman’s boot gets stuck in a small hole (a). The free-body diagram of the woman’s leg minus the lower part is illustrated in (b). The resultant stress distribution on the cross sec- tion BB9 is schematically shown in (c). Determine the axial stress versus axial strain curves of three specimens obtained from materials such as various fabrics, strings, springs, or leaves and branches. Quick-capture and digitize the data us- ing a computer and plot stress versus strain. If a specimen has a con- stant depth, like that of a fabric, one could use the parameter (force di- vided by the width of the specimen) as a substitute for stress. An elastic spring of stiffness k and force-free length Lo is at- tached to a plate at one end (Fig. The spring reaches steady-state length of L1 under the application of a large weight W1 at its free end. At that stage, the weight W1 is replaced with a smaller weight W while keeping the extended length of the spring constant. Show that the velocity v of the contracting spring is given by the following expression: v 5 [g/(k m)1/2] (m 2 m) sin ((k/m)1/2 t) 1 where m 5 W/g and m1 5 W1/g. To come up with a single velocity value for each differ- ent (m/m1) ratio, try two different definitions: (1) velocity v* is the max- imum velocity of mass m during the contraction of the spring, and (2) W1 L0 L1 L A W A A W W1 FIGURE P. Use the following parameter values in plotting v* as a func- tion of the relative load m/m1: m1 5 0. Compare your results with the force–velocity relationship of a con- tracting skeletal muscle fiber. Note that the contraction velocity V that was defined in the text is dimensionless. A 17-year-old girl with 5-cm tibial shortening underwent a single fracture limb lengthening (Fig. The limb-lengthening procedure on a patient whose left leg was 5 cm shorter than the right leg. F F 20o j j 20o d d1 W/6 W/6 x 1 W/2 W/2 d2 AA9 in the soft tissue when the lower leg is positioned horizontally im- mediately after the bones of the lower leg were cut into two? Determine the force FM produced by the principal abduc- tor muscle gluteus medius and the total hip joint force Fj during the standing position shown in Fig. The lever arm c of gluteus medius with respect to the center of rotation of the hip is equal to 7 cm. The femorotibial joint is not a simple hinge, but the bone force FR acts at a distance d 5 2. Compute the joint force FR and the tension T in the gluteus max- imus for an individual standing on one foot. A runner crushes down upon his or her heel with a briefly sustained but intense force that often reaches many times the body weight. Each heel strike sends shock waves through the body, causing ac- celerations as high as 15 g. Running is not the only mode of motion dur- ing which impulsive forces act on humans. Accidental falls are the lead- ing cause of death from injury among persons aged 65 years and older. Finally, it must be noted that car-crash injury is still the number one killer for adults under the age of 35 years. To that end, the mechanics of objects impacting on padded surfaces are of great interest in biomechanics. The risk of injury from striking an automobile dashboard is of obvious im- portance in everyday life. We illustrate how the impact forces affect the move- ment and motion of the human body. The analysis is based on the math- ematical relationship between impulse and momentum. If the force does not change direction during the time period Dt, the magnitude of the impulse is equal to the area under the iFi–time curve (Fig. The magnitude of the impulse z generated by F is equal to the area under the force–time curve. The linear momentum L of an object at time t was pre- viously defined as L 5 m vc (7. According to Newton’s second law, the equation of motion of the center of mass of an object is dL/dt 5SF where SF denotes the resulting force acting on the object. Integrating the equation of motion for the center of mass between time t 5 ti and t 5 tf, we obtain the following relationship: m vc 2 m vc 5Sz (7. The vec- torial sum of the impulse and the linear momentum before the impulse must be equal to the linear momentum after the impulse. According to this equation, the change in the linear mo- mentum of a body during the time interval Dt is equal to the impulse act- ing on the body during the same time interval (Fig. The linear mo- mentum of the body in the direction normal to the impulse remains unaffected. In some situations an external force acting on a body is large compared to other forces exerted on the body but the time interval during which the force acts is small. A force that becomes very large during a very small time interval is called an impulsive force. When an impulsive force acts on a body, there may be an appreciable alteration in velocity during the period of application of the force. If some of the external forces acting on the object during a time interval (tf 2 ti) are impulsive, we may neglect en- tirely the effect of all other external forces on the motion of the object in the same time interval. Although the velocities may be altered as a result of impulse, the change in the spatial position of an object is negligible. Determine the average impact force on a front-seat passenger who is (i) buckled and (ii) not buckled. Experments with dummies indi- cate that if a passenger were not to wear a seat belt, he or she would hit the windshield and that collision would take place in 1 ms. In this particular case, we assume the weight of the front-seat passenger to be 60 kg. Because the im- pulsive force from the collision is much greater than other forces acting on the front passenger (the weight of the passenger and the contact forces between the seat and the passenger), impulse z in both cases is equal to z 5 60 kg [0 2 (120 km/h)] e1 522000 kg?

Adduction, excessive ﬂexion, and sions per week postoperatively are associated with better abduction at the hip should be avoided if the joint has health outcomes. The patient should support no independence in bathing and transfers, family involve- more than 20% to 25% of total body weight on a cane. Early discharge and home rehabilitation should be considered for those with (1) good health (the absence of signiﬁcant medical prob- lems), (2) strong social supports (someone who can provide assistance), and (3) adequate performance of ambulation and activities of daily living within 2 weeks of surgery. The remainder may require more intensive therapy that can be effectively provided in a rehabilita- tion nursing facility. Lower Extremity Amputation Although most patients who experience a lower extrem- ity amputation (LEA) are between 51 and 69 years old, the age-related incidence of LEA in persons over age 80 has increased signiﬁcantly. The older person’s care is more complex after amputation because of upper extremity weakness, underlying cardiovascular problems, skin that is prone to breakdown, and poor balance mechanisms. Older persons are more likely to have subsequent amputations on the contralateral side. The elbow is ﬂexed 20° to 30° crucial role in managing these problems and in helping when holding the cane at the side. In frail older persons, the decision as to level of ampu- tation is often difﬁcult. Stair training begins during the second week 90% success rate for healing a transtibial amputation. Patients need to practice advancing the walker attempts should be made to avoid serial amputations about 20 to 30 cm, then advancing the weak leg, and then (e. Some older persons may ﬁnd it easier to transfemoral) because prolonged bed rest and its atten- advance the good leg ﬁrst, but this practice increases dant complications are more likely. Crutches are very difﬁcult for most There are three major types of lower extremity older persons to use.
