Block

 

in engineering:

(1) A unit of a mechanism in the form of a wheel with a groove around its circumference over which a cable or chain is drawn. It is used to change the direction of a tractive force and to obtain a force or velocity advantage; more rarely, to transfer a torque. Depending on their function, blocks are known as guide, balance, runner, and driving (for imparting rotary motion to a shaft) pulleys. In order to achieve a large force or velocity advantage, a lifting mechanism made up of a combination of blocks (a block and tackle) is used.

(2) A subassembly of a machine, consisting of several identical parts, such as a block of cylinders in an internal combustion engine or the spindle block in a multiple-spindle machine.

(3) A stone (concrete or ceramic) of large size (appreciably larger than a brick) used in the construction of buildings and for road surfacing.
