Incorrect Statement:
Grashofs rule states that for a planar crank-rocker four bar mechanism, the sum of the shortest and longest link lengths cannot be less than the sum of the remaining two link lengths.
Explanation:
Grashof's rule is a criterion for the mobility of a four-bar linkage. According to this rule, a four-bar linkage will be able to perform continuous rotation if the sum of the shortest and longest link lengths is less than or equal to the sum of the other two link lengths. In other words, if the sum of the shortest and longest links is greater than the sum of the other two links, the linkage will be unable to rotate continuously.
Therefore, the given statement is incorrect as it mentions that the sum of the shortest and longest link lengths cannot be less than the sum of the remaining two link lengths, which is the opposite of what Grashof's rule states.
Correct Statements:
- Inversions of a mechanism are created by fixing different links one at a time.
- Geneva mechanism is an intermittent motion device.
- Gruebler's criterion assumes mobility of a planar mechanism to be one.

Why not option d? Grubler's criterion says DOF= 3(N-1)-2L-H
Where is assumes dof of planar mechanism to be one?
