Theory of Machine A combination of kinematic pairs, joined in such a way that the relative motion between the links is completely constrained, is called a Mechanism Inversion Structure Kinematic chain Mechanism Inversion Structure Kinematic chain ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rigid body, under the action of external forces, can be replaced by two masses placed at a fixed distance apart. The two masses form an equivalent dynamical system, if All of these The center of gravity of the two masses coincides with that of the body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The sum of the two masses is equal to the total mass of body All of these The center of gravity of the two masses coincides with that of the body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body The sum of the two masses is equal to the total mass of body ANSWER DOWNLOAD EXAMIANS APP
