A deltoid linkage is a four bar mechanism which consists of two pairs of equal and adjacent links. It is a grashof linkage for which the sum of the lengths of the shortest link and the longest link is equal

## Double Crank Mechanism

Double Crank Mechanism is a four bar linkage. In this linkage, both the links pivoted to the fixed link rotates fully. It is a Grashof linkage for which the sum of the lengths of the shortest link and the largest

## Crank Rocker Mechanism

Crank Rocker Mechanism is a four bar linkage. In this linkage, the shortest link rotates fully while the other link pivoted to the fixed link oscillates. It is a Grashof linkage for which the sum of the lengths of the

## Difference between Double Rocker Mechanism and Triple Rocker Mechanism

Double rocker mechanism is a grashof linkage for which the sum of the lengths of the shortest link and the largest link is less than the sum of the lengths of the other two links. On the other hand, Triple

## Triple Rocker Mechanism

In Triple rocker mechanism, one link is fixed while the other three oscillates. It is a non grashof linkage for which the sum of the lengths of the shortest link and the longest link is greater than the sum of

## Double Rocker Mechanism

Double Rocker Mechanism is a four-bar mechanism. In this linkage, both the links pivoted to the fixed link oscillate. It is a Grashof linkage for which the sum of the lengths of the shortest link and the largest link is
