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 length of effective stroke of piston Reduce maximum opening of port to steam Cause withdrawing or throttling of steam All of the listed here Reduce length of effective stroke of piston Reduce maximum opening of port to steam Cause withdrawing or throttling of steam All of the listed here ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a reciprocating steam engine, when the crank has turned from inner dead centre through an angle θ, the angular velocity of the connecting rod is given by ω sinθ/(n² - cos²θ)1/2 ω cosθ/(n² - sin²θ)1/2 ω cosθ/(n² - cos²θ)1/2 ω sinθ/(n² - sin²θ)1/2 ω sinθ/(n² - cos²θ)1/2 ω cosθ/(n² - sin²θ)1/2 ω cosθ/(n² - cos²θ)1/2 ω sinθ/(n² - sin²θ)1/2 ANSWER DOWNLOAD EXAMIANS APP
