(Otomotiv) Found mostly in front-wheel-drive cars, and on some rear-wheel-drive cars with independent rear suspension systems, these special joints transmit engine power while allowing full steering and suspension movement. They are covered by black accordion boots that protect joints and hold grease
the place at which two things are joined together; in living organisms refers to the parts where two bones move one another, and the way those parts are put together
(n) An element in a kinematic model defining the constraints between two rigid parts of the assembly (called the links) Joints define how the links can move relative to each other, in rotation and translation
are fractures in the rock which have opened up perpendicular to the walls (or faces), generally without any shearing of one side past the other This process tends to produce very smooth even surfaces Preferential erosion along the joints in the Ithaca area is responsible for the rectilinear pattern of many of the gorges in the area
A fracture in a rock that exhibits no displacement across it (unlike a fault) Joints may be caused by shrinkage of igneous rocks as they cool in the solid state, or, in sediments, by regional extension or compression of sediment caused by earth movements
A semi-finished product used in the manufacture of brooches or any item which includes a pin for fastening The joint holds the -pin at one end allowing it to swivel for opening and closing
In architecture, the connection of construction materials. All joints are carefully detailed by the architect with concern for strength, movement, penetration by the elements, and incompatibilities. The term joinery refers especially to carpentry. Common types of joints include the dovetail, used for interlocking two flat members at right angles, as in the sides of a drawer; the doweled joint, in which doweling is employed for mechanical strength; and the mortise and tenon, in which a projecting piece fits into a groove, used to join a horizontal member with the vertical member of a frame
(Otomotiv) Couplings located at either end of the driveshaft on a rearwheel drive vehicle that allow the shaft to move freely, without affecting the more rigid transmission shaft, and to absorb the movement of the axle and wheels. Also called U-joints. On cars with transverse engines, these are called constant velocity joints
