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 Cause withdrawing or throttling of steam Reduce maximum opening of port to steam All of these Reduce length of effective stroke of piston Cause withdrawing or throttling of steam Reduce maximum opening of port to steam All of these Reduce length of effective stroke of piston ANSWER DOWNLOAD EXAMIANS APP
