Theory of Machine A friction circle is a circle drawn when a journal rotates in a bearing. Its radius depends upon the coefficient of friction and the Angular velocity of journal Clearance between journal and bearing Magnitude of the forces on journal Radius of journal Angular velocity of journal Clearance between journal and bearing Magnitude of the forces on journal Radius of journal ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The effort of a Porter governor is equal to (where c = Percentage increase in speed, m = Mass of ball, and M = Mass on the sleeve) c (m + M) g c (m - M) g c/(m + M) g c/(m - M) g c (m + M) g c (m - M) g c/(m + M) g c/(m - M) g ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine For two governors A and B, the lift of sleeve of governor A is more than that of governor B, for a given fractional change in speed. It indicates that None of these Governor B is more sensitive than governor A Both governors A and B are equally sensitive Governor A is more sensitive than governor B None of these Governor B is more sensitive than governor A Both governors A and B are equally sensitive Governor A is more sensitive than governor B ANSWER DOWNLOAD EXAMIANS APP
