What will be the minimum number of links required to form a kinematic chain considering all the pairs as lower pairs
Show Hint
Remember that a three-link system forms a rigid structure (triangle), while a four-link system with lower pairs provides one degree of freedom.
This makes the four-bar chain the simplest kinematic chain used in mechanical linkages.
