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 Inversion Kinematic chain Structure Mechanism Inversion Kinematic chain Structure Mechanism ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a steam engine, one method of obtaining the earlier cut-off with a simple slide valve is by increasing the angle of advance of the eccentric while the throw of the eccentric, steam lap and exhaust lap are kept constant. This method will All of these Reduce maximum opening of port to steam Cause withdrawing or throttling of steam Reduce length of effective stroke of piston All of these Reduce maximum opening of port to steam Cause withdrawing or throttling of steam Reduce length of effective stroke of piston ANSWER DOWNLOAD EXAMIANS APP
