Which if the following key is under compression rather than in being shear when under load?

Which if the following key is under compression rather than in being shear when under load? Correct Answer Barth

  • A key is a machine member employed at the interface of a pair of mating male and female circular cross-sectioned members to prevent relative angular motion between these mating members. The key fits into mating grooves in the shaft and mating member called the keyway and transmit torque by shear across the key.
  • Barth key is a modification of rectangular key which has two beveled surfaces. The beveled surface ensures that the key will fit tightly. This key is usually under compression rather than shear.
