The mobility of the linkage can be
determined by the help of ________ .
Euler’s equation
Grubler’s equation
Redundant links
velocity diagram
Grubler’s equation
●The mobility of the linkage (degree
of freedom) can be determined by the help of Grubler’s equation, which is,
F = 3(l - 1) - 2j - h
●A system may have one or more links
which do not introduce any extra constraint. Such links are known as redundant
links and should not be counted to find DOF.
●Velocity diagrams are used to find
different velocity of different links.
Hence, the correct option is (B).
