Q10: When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure. The force of the weight of a person is supported by the force n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find O for two persons with mass 30kg for the first and 90 kg for the second. 18.0 cm 25.0 cm

5. The figure below represents the anatomy of the lower limb when balanced on your toes and the body weight acts through the tibia. The Achilles Tendon makes an angle (0) of 8° with the vertical and for this foot x1 is 6.2 cm and x2 is 12.3 cm. Calf Muscle Tibia Achilles Tendon Calculate the tension (T) in the Achilles Tendon if a 70 kg man stands on the toes of both feet. Using the values in this example what is the mechanical advantage for this lever and describe what that means in terms of the efficiency of the lever.

Figure 1 shows a simple system to lift a heavy load. The dimensions a = 3.6 m and b = 1.2 m. The mass of the bar and counterweight is 45000 g, and their weight W acts at the point as shown. The mass of the load being lifted is 20000g (a) (b) If the load is just above the ground, determine the vertical force the person must exert to support the system. If the load is 1 m above the ground, determine the vertical force the person must exert to support the system. 25° Figure 1 20000 g W
Equilibrium of Concurrent Force System. The piston of a reciprocating engine exerts a force of 175 kN on the crosshead when the crank is 45° (angle B) past TDC.

The figure on the left, below, shows a non-uniform bent rod with a mass of 5 kg. Your job is to determine the location of the center of gravity of this rod. You design an experiment: you connect a pin and cable to the rod such that it safely stays in static equilibrium under a force P that you apply. Then, you apply forces between 0-100 N, and measure the tension force on the cable using a cable tension meter. The results of your experiment are shown in the figure, on the right. Using this experiment, calculate (approximately) the horizontal distance (x in the figure) between point A and the center of gravity G of the bent rod.
