Question 1

Match the items in columns I and II.

Question 2

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 3

For the four-bar linkage shown in the figure, the angular velocity of link AB is 1 rad/s. The length of link CD is 1.5 times the length of link AB. In the configuration shown, the angular velocity of link CD in rad/s is

Question 4

Block 2 slides outward on link 1 at a uniform velocity of 6 m/s as shown in the figure. Link 1 is rotating at a constant angular velocity of 20 radians/s counterclockwise. The magnitude of the total acceleration (in m/s²) of point P of the block with respect to fixed point O is ___.

Question 5

The input link O₂P of a four bar linkage is rotated at 2 rad/s counter clockwise direction as shown below. The angular velocity of the coupler PQ in rad/s, at an instant when ∠O₄O₂P = 180°, is

Question 6

A slider crank mechanism is rotating with angular velocity of 20 rad/s having crank angle of 60 degree with positive x axis of the slider direction. If the length of the coupler is 100 mm and radius of the crank is 20 mm. Find the angular velocity of the coupler (in rad/s) _____________.
