Examples of Application
In biomechanical research the instant center of rotation is observed for the functioning of the joints in the upper and lower extremities. For example in analysing the knee, ankle, or shoulder joints. Such knowledge assists in developing artificial joints and prosthesis, such as elbow or finger joints.
Study of the joints of horses: "...velocity vectors determined from the instant centers of rotation indicated that the joint surfaces slide on each other.".
Studies on turning a vessel moving through water.
The braking characteristiscs of a car may be improved by varying the design of a brake pedal mechanism.
Designing the suspension of a bicycle, or of a car.
In the case of the coupler link in a four-bar linkage, such as a double wishbone suspension in front view, the perpendiculars to the velocity lie along the links joining the grounded link to the coupler link. This construction is used to establish the kinematic Roll center of the suspension.

Famous quotes containing the words examples of, examples and/or application:
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
“Histories are more full of examples of the fidelity of dogs than of friends.”
—Alexander Pope (1688–1744)
“We will not be imposed upon by this vast application of forces. We believe that most things will have to be accomplished still by the application called Industry. We are rather pleased, after all, to consider the small private, but both constant and accumulated, force which stands behind every spade in the field. This it is that makes the valleys shine, and the deserts really bloom.”
—Henry David Thoreau (1817–1862)
