Explain what it means for parts to be "keyed together."
What will be an ideal response?
Parts that are assembled and disassembled in a particular position to transmit motion from one member to another are keyed together. This means a square or flat piece of steel is partly seated in a shaft or groove called a keyseat. The key extends an equal distance into a corresponding groove (keyway) in a second member (hub). Another general type of key is semicircular in shape. It fits into a round machined groove in the shaft. This type is known as a Woodruff key.
