A leg is a weight bearing and locomotive structure, usually having a columnar shape. During locomotion, legs function as "extensible struts" - the combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional "hip" joint.
As an anatomical animal structure it is used for locomotion. The distal end is often modified to distribute force (such as a foot). Most animals have an even number of legs.
As a component of furniture it is used for the economy of materials needed to provide the support for the useful surface, the table top or chair seat.
Famous quotes containing the word leg:
“A good leg will fall, a straight back will stoop, a black beard will turn white, a fair face will wither, a full eye will wax hollow, but a good heart, Kate, is the sun and the moonor rather the sun and not the moon, for it shines bright and never changes, but keeps his course truly.”
—William Shakespeare (15641616)
“A sympathetic person is placed in the dilemma of a swimmer among drowning men, who all catch at him, and if he give so much as a leg or a finger, they will drown him. They wish to be saved from the mischief of their vices, but not from their vices.”
—Ralph Waldo Emerson (18031882)
“I keep thinking that what I need
to do is buy my leg back.
Surely it is for sale somewhere,
poor broken tool, poor ornament.
It might be in a store somewhere beside a ladys scarf.”
—Anne Sexton (19281974)
