What's the difference between pulley and wheel?

Pulley


Definition:

  • (v. t.) A wheel with a broad rim, or grooved rim, for transmitting power from, or imparting power to, the different parts of machinery, or for changing the direction of motion, by means of a belt, cord, rope, or chain.
  • (b. t.) To raise or lift by means of a pulley.
