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 1/8 1/24 4/15 12 1/8 1/24 4/15 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm 45 mm Slightly more than 95 mm Slightly less than 95 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
