Here we will use the physical pendulum as a model for the swinging leg to compute this same quantity order 20 mg tadacip otc impotence after 60. This model is purchase generic tadacip on-line impotence of organic origin, of course buy cheap tadacip 20mg line erectile dysfunction urologist new york, not strictly correct because in running the legs swing not only at the hips but also at the knees extra super avana 260 mg on-line. We will now outline a method for calculating the energy expended in swinging the legs buy cheap proscar. During each step of the run, the leg is accelerated to a maximum angular velocity max. In our pendulum model, this maximum angular velocity is reached as the foot swings past the vertical position 0 (see Fig. The rotational kinetic energy at this point is the energy provided by the leg muscles in each step of the run. From the rate of running, we can compute the period of oscillation T for the leg modeled as a pendulum. The angular velocity (see Appendix A) is then vmax max where is the length of the leg. In computing the period T, we must note that the number of steps per second each leg executes is one half of the total num- ber of steps per second. In Exercise 4-8, it is shown that, based on the phys- ical pendulum model for running, the amount of work done during each step is 1. Considering that both approaches are approximate, the agreement is certainly acceptable. In calculating the energy requirements of walking and running, we assumed that the kinetic energy imparted to the leg is fully (frictionally) dis- sipated as the motion of the limb is halted within each step cycle. The assumption of full energy dissipation at each step results in an overestimate of the energy requirements for walking and run- ning. This energy overestimate is balanced by the underestimate due to the neglecting of movement of the center of mass up and down during walking and running as is discussed in following Sections 4. More detailed and accurate descriptions can be found in various technical journals. However, the basic approach in the various methods of anal- ysis is similar in that the highly complex interactive musculoskeletal system involved in walking and/or running is represented by a simplied structure that is amenable to mathematical analysis. In our treatment of walking and running we considered only the pendulum- like motion of the legs. A way to model the center of mass motion in walking is to consider the motion of the center of mass during the course of a step. Consider the start of the step when both feet are on the ground with one foot ahead of the other. At this point the center of mass is between the two feet and is at its lowest position (see Fig.

The maximum angular velocity max can be calculated from the maximum linear velocity vmax at the center of the wing vmax max (6 purchase tadacip without prescription erectile dysfunction caused by heart medication. When the wings are decelerated toward the end of the stroke order 20 mg tadacip visa impotence problems, this energy must be dissipated order tadacip toronto erectile dysfunction 17. During the downstroke kamagra 50mg mastercard, the kinetic energy is dissipated by the muscles themselves and is converted into heat cheap 30 mg vytorin fast delivery. The wing joints of these insects contain a pad of elastic, rubberlike protein called resilin (Fig. The kinetic energy of the wing is converted into potential energy in the stretched resilin, which stores the energy much like a spring. Using a few simplifying assumptions, we can calculate the amount of energy stored in the stretched resilin. Although the resilin is bent into a com- plex shape, we will assume in our calculation that it is a straight rod of area A and length. Furthermore, we will assume that throughout the stretch the resilin obeys Hookes law. This is not strictly true as the resilin is stretched by a considerable amount and therefore both the area and Youngs modulus change in the process of stretching. Typically, in an insect the size of a bee the volume of the resilin may be equivalent to a cylinder 2 102 cm long and 4 104 cm2 in area. We will assume that the length of the resilin rod is increased by 50% when stretched. Experiments show that as much as 80% of the kinetic energy of the wing may be stored in the resilin. The hind legs of the ea, for exam- ple, also contain resilin, which stores energy for jumping (see Exercise 6-3). Compute the force on the body of the insect that must be generated during the downward wing stroke to keep the insect hovering. Referring to the discussion in the text, compute the point of attachment to the wing of muscle B in Fig. Assume that the shape of the resilin in each leg of the ea is equivalent to a cylinder 2 102 cm long and 104 cm2 in area. If the change in the length of the resilin is 102 cm, calculate the energy stored in the resilin. How large would these pads have to be in order for them to store 1 enough energy for a m jump? In the next three chapters, we will discuss the behavior of liquids and gases, both of which play an important role in the life sci- ences. The dierences in the physical properties of solids, liquids, and gases are explained in terms of the forces that bind the molecules. In a solid, the molecules are rigidly bound; a solid therefore has a denite shape and vol- ume.
