Theory of Machine In a steam engine, the earlier cut-off with a simple slide valve may be obtained by increasing the steam lap and the angle of advance of the eccentric but keeping constant the travel and lead of the valve, this method will Reduce maximum opening of port to steam Cause withdrawing or throttling of steam Reduce length of effective stroke of piston All of the listed here Reduce maximum opening of port to steam Cause withdrawing or throttling of steam Reduce length of effective stroke of piston All of the listed here ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Two lower pairs and two additional links Any one of these Two lower pairs and one additional link One lower pair and two additional links Two lower pairs and two additional links Any one of these Two lower pairs and one additional link One lower pair and two additional links ANSWER DOWNLOAD EXAMIANS APP
