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 There are six gears A, B, C, D, E and F in a compound train. The numbers of teeth in the gears are 20, 60, 30, 80, 25 and 75 respectively. The ratio of angular speeds of the driven (F) to the driver (A) of the drive is 12 4/15 1/8 1/24 12 4/15 1/8 1/24 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A motor car moving at a certain speed takes a left turn in a curved path. If the engine rotates in the same direction as that of wheels, men due to centrifugal force The reaction on the outer wheels increases and on the inner wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on the rear wheels increases and on the front wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases The reaction on the outer wheels increases and on the inner wheels decreases The reaction on the front wheels increases and on the rear wheels decreases The reaction on the rear wheels increases and on the front wheels decreases The reaction on me inner wheels increases and on the outer wheels decreases ANSWER DOWNLOAD EXAMIANS APP
