Question

When the connection between the elements forming a pair is such that the constrained motion is not completed by itself, but by some other means, the motion is said to be a completely constrained motion.

(a) True

(b) False

The question was asked in examination.

I need to ask this question from Kinematic Link or Element in chapter Simple Mechanisms of Machine Kinematics

Answer 1

Right choice is (b) False

To elaborate: When the motion between a pair is limited to a definite direction irrespective of the direction of force applied, then the motion is said to be a completely constrained motion.

When the connection between the elements forming a pair is such that the constrained motion is not completed by itself, but by some other means, the motion is said to be a successfully constrained motion.
