Gibbons move through the trees by swinging from successive handholds, as we have seen. To increase their speed, gibbons may bring their legs close to their bodies. How does this help them move more quickly?
Tarzan's best monkey friend, JoJo, hurt his hand awhile ago. He was swinging around the jungle and his hand got tangled in some vines. He has been resting it for awhile and has had to walk around the jungle instead of swinging through the jungle. Tarzan advised him that his hand should be healed by now and that he should start exercising it slowly before he tries swinging around on vines. JoJo has been squeezing his favorite rubber ball with his injured hand in order to build up its strength. Tarzan has been keeping track of his progress, but living in the jungle, rain has smudged his data table. Help Tarzan complete his data table using what you know about the behavior of balls that act like springs and the restoring force.
Calculate what each smudge on the table should be.
smudge A _____N/m
smudge B_____N
smudge C_____N
smudge D_____cm
Most injuries to the shoulder will require rehab and physical therapy. Pendulum exercises are a great way to
increase strength and improve flexibility and range of motion in an injured shoulder. Here, the patient bends
forward until their back is horizontal. The injured arm is hung vertically downward and is allowed to swing
freely back and forth like a pendulum (see the figure). Treat the arm (length of 69 cm) in the figure as a
physical pendulum - a uniform rod rotating about an axis through one of its ends - and calculate the period of
the arm's small oscillations.

The lower end is tied to the floor, and the upper end is tied to a small set of wheels through a slot in a track on which the wheels move (Fig. P18.76). The wheels have a mass that is negligible compared with that of the siring, and they roll without friction on the track so that the upper end of the string is essentially free.

- An elephant’s legs have a reasonably uniform cross section from top to bottom, and they are quite long, pivoting high on the animal’s body. When an elephant moves at a walk, it uses very little energy to bring its legsforward, simply allowing them to swing like pendulums. For fluid walking motion, this time should be half the time for a complete stride; as soon as the right leg finishes swinging forward, the elephant plants the right foot and begins swinging the left leg forward.a. An elephant has legs that stretch 2.3 m from its shoulders to the ground. How much time is required for one leg to swing forward after completing a stride?b. What would you predict for this elephant’s stride frequency? That is, how many steps per minute will the elephant take?arrow_forwardOrangutans can move by brachiation, swinging like a pendulum beneath successive handholds.
