Mechanical Engineering QUESTION #2494
Question 1
The number of driver links in a mechanism equals:
  • The number of grounded joints
  • The number of degrees of freedom (mobility) \(M\) of the mechanism✔️
  • The total number of links minus one
  • The number of output links
Correct Answer Explanation
By definition, the number of driver links equals the DOF (mobility) \(M\) of the mechanism. Each driver link provides one independent input.
