Question

The example of successfully constrained motion is a

(a) motion of an I.C. engine valve

(b) motion of the shaft between a foot-step bearing

(c) piston reciprocating inside an engine cylinder

(d) all of the mentioned

The question was posed to me in my homework.

My question is taken from Kinematic Link or Element topic in portion Simple Mechanisms of Machine Kinematics

Answer 1

Correct option is (d) all of the mentioned

Explanation: 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. so, the above examples have successfully constrained motion.
