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