Question 2

The correct relation between number of links and number of pairs for a kinematic chain is____.
(L is number of links, p is number pairs)

Question 3

The magnitude of the coriolis component of acceleration of a slider moving at a velocity V on a link rotating at angular speed $Description: Description: E:\Gate\SSC JE Mechanical Part 1\Practice-Set-1_files\image233.png$ is.

Question 4

The center of gravity of the coupler link in a 4-bar mechanism would experience _______.

Question 5

Coriolis component of acceleration is always _____.

Question 6

How many degrees of freedom does the below mechanism have?

Question 7

Two links are shown in Coriolis component figure where first link speed with respect to second link speed is 15 m/sec. If second link rotates at fixed speed of 80 rpm, then find magnitude of Coriolis component of acceleration of first link?

Question 8

In a single slider crank mechanism, length of crank and connecting rod are 60 mm and 180 mm, respectively. Crank is making 60 rotations per minute. Find the velocity of the slider at the moment __________, when crank is perpendicular to the line of stoke.

Question 9

For the figure shown below, at which position of

will the absolute velocity of end B of the coupler will be equal to the absolute velocity of the end A of the coupler?

Question 10
