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 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base) cotφ - cotα = c/b cosφ - sinα = c/b sinφ + sinα = b/c tanφ + cotα = b/c cotφ - cotα = c/b cosφ - sinα = c/b sinφ + sinα = b/c tanφ + cotα = b/c ANSWER DOWNLOAD EXAMIANS APP
