What is a Constrained Motion?
Constrained Motion is defined as a mechanical pair which is having definite motion with respect to another element.
Types of Constrained Motion:
There are three types of Constrained Motion:
- Completely constrained
- Partially or Successfully constrained motion and
- Incompletely constrained motion
1. Completely Constrained Motion:
Completely Constrained Motion is defined as the motion between the pair that takes place in a definite direction irrespective of the direction of the force applied, Therefore it is known as Completely Constrained motion.
- Square bar in a square hole
- Shaft with a collar at each end in the circular hole.
- A piston in the cylinder of an IC engine.
2. Partially or Successfully constrained motion:
In a partially or successfully constrained motion, the motion between a pair is not completed by itself but by some other means. Let’s understand by an example
Example: The motion of the shaft in a footstep bearing becomes successfully constrained motion when a compressive load is applied.
3. Incompletely constrained motion:
The motion between a pair takes place in more than one direction.
Example: Circular shaft in a circular hole, as it may either rotate or slide in a hole. Both motions have no relationship with other.
