The centre of gravity of a coupler link in a four bar chain mechanism will experience.

The centre of gravity of a coupler link in a four bar chain mechanism will experience. Correct Answer Both linear and angular acceleration

Concept:

Coupler: a link or a rod that is transmitting the power between two rotating mechanisms or a rotating part and a reciprocating part.

From the above figure, we can see that link  3 is coupler which is transmitting the power between link(4) and link(2).

From the observation, it can be clearly said that the center of gravity of link 3 is having both linear and angular acceleration as link 3 is having linear as well as angular motion.

Hence option(4) is correct.

Find out the proper order for the four sentences. S1: Most people who have come close to death say they remember nothing. P. It may permanently change a person’s perceptions of what is real and important Q. The near-death experience is among the most powerful experiences that a person can have. R. That ‘something’ might be a near-death experience. S. However, a third or more may later report that ‘something happened.’ S6: However, one extraordinary aspect of near-death experience is that a person’s culture, religion, race or education does not affect the pattern of the experience.
