Question 1

consider the following statements for a 4-cyclinder in line engine whose cranks are arranged at regular intervals of

:
1) There are 8 possible firing orders for the engine.
2) Primary force will remain unbalanced for some firing orders.
which of the following statements concerning centrifugal governors:

Question 2

What is the condition for dynamic balancing of a shaft-rotor system?

Question 3

In Gyroscopic Couple, direction of angular momentum is similar to:

Question 4

Statement (I): when a flat force follower is used, it would be preferable to provide an offset in the plane perpendicular to the plane of rotation of the cam.
Statement (II): Because of the offset, the follower is made to rotate continuously about its axis which in turn avoids jamming of the follower in its guide while moving up or down, reduces the wear of the follower flat surface distributes the wear uniformly.

Question 5

While designing a cam, pressure angle is one of the most important parameters which is inversely proportional to

Question 6

In the figure, link 2 rotates with constant annular velocity w2. A slider link 3 moves outwards with a constant relative velocity Vqp where Q is a Point on slider 3 and P is a point on link 2. The magnitude and direction of Coriolis component of acceleration is given by

Question 7

Which among the following information regarding the 4 bar mechanism is correct?

Question 8

Pick up the right statement. A flywheel

Question 9

In a crank and slotted lever quick return motion mechanism, the length of the fixed link is 160 mm and the driving crank is 80 mm long. The ratio of time taken by cutting and return strokes is
