The mechanism forms a structure, when the number of degrees of freedom (n) is equal to Correct Answer 0

When n = 0, then the mechanism forms a structure and no relative motion between the links is possible. When n = 1, then the mechanism can be driven by a single input motion. When n = 2, then two separate input motions are necessary to produce constrained motion for the mechanism. When n = – 1 or less, then there are redundant constraints in the chain and it forms a statically indeterminate structure.

The popular notion that a tree's age can be determined by counting number of internal rings in its trunk is generally true. Howeevr, to help regulate the internal temperature of the tree, the outermost layers of wood of the Brazilian ash often →peel away when the temperature exceeds 95 degrees Fahrenheit, leaving the tree with fewer rings than it would otherwise have.
