Topic: Theory of Machines
Inversion of a mechanism is
- A. Changing of a higher pair to lower pair
- B. Obtained by fixing different links in a kinematic chain
- C. Turning it upside down
- D. Obtained by reversing the input and output motion
Answer: B. Obtained by fixing different links in a kinematic chain
Explanation: In kinematics, an inversion of a mechanism is produced by choosing different links to be the fixed frame. If a kinematic chain has $n$ links, it can theoretically yield $n$ different mechanisms by fixing each link one by one.
