    DEGREES OF FREEDOM —–SHEET 3

    DEGREES OF FREEDOM —–SHEET 3 KINEMATIC CONSTRAINTS The motion of the independent rigid bodies can be controlled with kinematic constraints. A Kinematic constraint  between two or more rigid bodies decreases the degrees of freedom for the connected rigid bodies. Main classification of kinematic pairs falls in three categories. However these three categories are further sub divided […]

    DEGREES OF FREEDOM—–SHEET 2

    DEGREES OF FREEDOM—–SHEET 2 DEGREES OF FREEDOM FOR  A GENERAL KINEMATIC CHAIN Equation for the degree of freedom F = 3n—3j-3 Where F is the overall number of degrees of freedom for the kinematic chain, n is the number of links (including the fixed link), j is the number of sliding or rotating pairs with […]

    DEGREES OF FREEDOM—————SHEET 1

    DEGREES OF FREEDOM—————SHEET 1 DEFINITION: IT IS THE MINIMUM NUMBER OF INDEPENDENT VARIABLES TO DEFINE A SYSTEM COMPLETELY. OR IT IS NUMBER OF VARIABLES WHICH ARE FREE TO VARY IN A SYSTEM. OR IT IS NUMBER OF INDEPENDENT MOTIONS A BODY CAN HAVE TO DEFINE A SYSTEM COMPLETELY. BASIC DEGREES OF FREEDOM FOR A SYSTEM UNDER […]
