Theory of Machine The inversion of a mechanism is Obtained by reversing the input and output motion Changing of a higher pair to a lower pair Obtained by fixing different links in a kinematic chain Turning its upside down Obtained by reversing the input and output motion Changing of a higher pair to a lower pair Obtained by fixing different links in a kinematic chain Turning its upside down 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 Reduce maximum opening of port to steam All of these Cause withdrawing or throttling of steam Reduce length of effective stroke of piston Reduce maximum opening of port to steam All of these Cause withdrawing or throttling of steam Reduce length of effective stroke of piston ANSWER DOWNLOAD EXAMIANS APP
