Mechanical Engineering QUESTION #2481
Question 1
A 'lower kinematic pair' as defined by Reuleaux has what type of contact between its elements?
  • Point contact
  • Curve (line) contact
  • Surface contact✔️
  • No direct contact (magnetic coupling)
Correct Answer Explanation
Reuleaux coined 'lower kinematic pair' for joints with surface (area) contact, such as revolute and prismatic pairs. Lower pairs have the practical advantage of better lubricant retention.
