Answer:

Woodruff key permits the b) Radial movement between the shaft and the hub.

Explanation:

  • A woodruff key is a kind of key that is semi-circular in shape. This resembles a half-moon shape so-called a Half-moon key.
  • It is a machine key that fits well into circular recesses in the shaft, usually machined by a keyway cutter.
  • Such keys prevent gears, hubs and other components from moving independently of a rotating spindle or shaft.
  • In most cases, woodruff keys are used in machine tools because it allows radial movement only and does not permit axial movement.

Hence option b) Radial is correct.
