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 All of the listed here Cause withdrawing or throttling of steam Reduce length of effective stroke of piston Reduce maximum opening of port to steam All of the listed here Cause withdrawing or throttling of steam Reduce length of effective stroke of piston ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are directly proportional to the speed Effects of unbalances are proportional to the square of the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds ANSWER DOWNLOAD EXAMIANS APP
