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 minimum length of the coupler will be 45 mm Slightly less than 45 mm Slightly more than 45 mm 95 mm 45 mm Slightly less than 45 mm Slightly more than 45 mm 95 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A thin circular disc is rolling with a uniform linear speed, along a straight path on a plane surface. Which of the following statement is correct in this regard? 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 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same Will change Will not occur Could change or remain unaltered depending on which link is fixed Will remain same 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 4/15 12 1/8 1/24 4/15 12 1/8 1/24 ANSWER DOWNLOAD EXAMIANS APP
