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 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 Reduce maximum opening of port to steam ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is Slightly less than 95 mm Slightly more than 95 mm 45 mm 95 mm Slightly less than 95 mm Slightly more than 95 mm 45 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
