Question

For the description of machine, mechanism, link and parts, ( ) is correct.

A.Parts is motion element B.Link is manufacturing element

C.Machine and mechanism are machinery D.Maybe there is no frame in a mechanism

Answer 1

For a description of machine there is requirement of frame which should have relative motive to each of its parts.

 A FRAME IS CALLED A MACHINE IF THEY HAVE RELATIVE MOTION OTHERWISE THEY CALLED STRUCTURE .

SO FOR THE DESCRIPTION OF MACHINE . FRAME IS REQUIRED 

MACHINE IS A COMBINATION OF PART AND LINKS , SO ONE LINK AND PARTS CAN NOT DESCRIBE THE MACHINE .

AND TO RUN A MACHINE THERE IS REQUIREMENT OF MACHANISM ,

HENCE OPTION [ C ] IS CORRECT .
