Question 1
Block ‘P’ slides outward on link at a velocity of 5 m/sec in a given instant as shown in figure. Link is rotating at an angular velocity of 25 rad/sec clockwise and having an Angular acceleration of 200 rad/sec2 in counterclockwise direction & also a radially outward acceleration of slider is 150 m/sec2 the magnitude of total acceleration of point slider is ____ m/sec2
Question 2
Two links have angular velocity of 20 rad/s and 15 rad/s both in opposite directions. If the radius of the pin at O is 10mm, O is point where two links are connected, determine the rubbing velocity at the joint____?
Question 3
A straight link has a straight slot along the length of the link in which a sliding block is free to slide. The slotted link is rotating at uniform angular velocity of 10 rad/s about one of its ends. The sliding block in the link is also moving outwards at a uniform speed of 5 m/s relative to the slotted link. What is the magnitude of acceleration of the slider in a direction perpendicular to the link _________?
Question 4
The below figure shows a four bar mechanism. If the radial acceleration of the point C is 5 cm/s2 and velocity of point B is shown in figure, then the length of the link CD is __________ cm. 
Question 5
For a mechanism having 6 links and 7 joints the number instantaneous centre is ( IC is a point at which a particular link is assumed to be a rotational motion about that point)
