African elephants are the largest land animals. They consume approximately 10% of their body weight in food each day, which for an adult male, can be 1000 lb. of vegetation! Their diet consists mostly of grasses, bamboo, tree bark, and fruit. They also like to dine on tree leaves. To reach them, they often stand up on their hind legs and extend their trunks (see the figure). The elephant in the figure is in equilibrium. The location of the elephant's center of mass is shown, and the axis of rotation has been chosen to correspond to the hi joint. The forces in the elephant's free-body diagram are shown, and there is a static friction force between the elephant's back feet and the ground. Use the following information and calculate the magnitude of the tension in the elephant's trunk T (m = 4540 kg, FN -rfs=133 cm, reg -76.0 cm, r = 229 cm).

There is a disk of cartilage between each pair of vertebrae in your spine. Suppose a disk is 0.50 cm thick and 4.0 cm in diameter. If this disk supports half the weight of a 65 kg person, by what fraction of its thickness does the disk compress?
When you bend your knee, the quadriceps muscle is stretched. This increases the tension in the quadriceps tendon attached to your kneecap (patella), which, in turn, increases the tension in the patella tendon that attaches your kneecap to your lower leg bone (tibia). Simultaneously, the end of your upper leg bone (femur) pushes outward on the patella. Shown is how these parts of a knee joint are arranged. What size force does the femur exert on the kneecap if the tendons are oriented as in the figure and the tension in each tendon is 60 N?
The left end of a spring is attached to a wall. When Bob pulls on the right end with a 200N force, he stretches the spring by 20 cm. The same spring is then used for a tug of war between Bob and Carlos. Each pulls on his end of the spring with a 200N force. How far does the spring stretch. Explain
Suppose the humerus is reduced uniformly in size by a factor of two. This means that both the length and diameter arehalved. What is the amount of stretch in this case?
Unlike most of the other muscles in our bodies, the masseter muscle in the jaw, as illustrated in the figure, is attached relatively far from the joint, enabling very large forces to be exerted by the back teeth. This is shown in the figure below, where a person is biting down on a bullet placed between the back teeth. (F, = 320 N and r, = 4.7 cm.) = 2.9 cm M Masseter muscle reaction (a) Using the information in the figure, calculate the magnitude of the force exerted by the teeth on the bullet. (b) Calculate magnitude of the force on the joint. N
When a person feels that he is about to fall, he will often put out his hand to try to break the fall. Explain why this natural reaction usually leads to bruises or minor broken bones such as in the wrists instead of major broken bones such as the skull.
Why does the suspended spring stretch more at the top than at the bottom?
Only with great difficulty can you crush an egg when squeezing it along its long axis, but it breaks easily if you squeeze it sideways. Why?
1 b F2 1 1 FR F1 b. The figure above shows a crane tower on site at the HWY 1 expansion and Stoney Trail extension in NW Calgary. You are a design engineer working for the company supplying cranes for the contractors and you have been asked to evaluate the tower design. The crane tower supporting the pulley is designed so that the resultant force from the cable tension running over the pulley is oriented along the tower axis. Note: The tension in the cable is the same on both sides so ||Fill = ||F2l|| = T.
Equilibrium: The mobile shown in the figure is perfectly balanced, and the horizontal supports have insignificant masses. What must be the masses of the suspended objects m 1, m 2, and m 3 to maintain balance? m 1, m 2, m 3=
Scientists have studied how snakes grip and climb ropes. In one study, they found that an important characteristic of a rope is its "compliance"--that is, how easily the rope, while under tension, can be flexed. (Figure 1) shows how scientists measured a rope's compliance by attaching it to two strings, each supporting an identical mass mm. The lower part of the rope is held under tension by a spring (not shown). The strings contort the rope so that its middle section lies at angle θ. For θ = 45∘ and mm = 400 g, what is the tension T2 in the middle part of the rope?
