The centre of the disc has centrifugal acceleration All points of the disc have the same velocity The centre of the disc has zero acceleration The point on the disc making contact with the plane surface has zero acceleration The centre of the disc has centrifugal acceleration All points of the disc have the same velocity The centre of the disc has zero acceleration The point on the disc making contact with the plane surface has zero acceleration ANSWER DOWNLOAD EXAMIANS APP
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 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 Reduce length of effective stroke of piston ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The ratio of height of Porter governor (when length of arms and links are equal) to the height of Watt's governor is (where m = Mass of the ball, and M = Mass on the sleeve) (m + M)/m M/(m + M) (m + M)/M m/(m + M) (m + M)/m M/(m + M) (m + M)/M m/(m + M) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the crank is at the outer dead centre, in a reciprocating steam engine, then the acceleration of the piston will be ω² r {n/(n - 1)} ω² r {n/(n + 1)} ω² r {(n - 1)/n} ω² r {(n + 1)/n} ω² r {n/(n - 1)} ω² r {n/(n + 1)} ω² r {(n - 1)/n} ω² r {(n + 1)/n} ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when a is +ve and b is also +ve a is +ve and b = 0 a = 0 and b is +ve a is +ve and b is -ve a is +ve and b is also +ve a is +ve and b = 0 a = 0 and b is +ve a is +ve and b is -ve ANSWER DOWNLOAD EXAMIANS APP
