Correct Answer - Option 4 : 10

Explanation:

Inversion:

• If one of the links is fixed in a kinematic chain, it is called a mechanism. So, we can obtain as many mechanisms as the number of links (n inversions from a kinematic chain having ‘n’ number of links) in a kinematic chain.
• This method of obtaining different mechanisms by fixing different links in a kinematic chain is known as inversion of the mechanism.
• In This question as there are 10 links, hence there will be 10 number of possible inversions.
• In the process of inversion, the relative motions of the links of the mechanisms produced remain unchanged.

 INVERSION Four Bar Chain Mechanism Beam Engine (crank and lever mechanism) Coupling rod of a locomotive (double crank mechanism) Watt’s Indicator (Double lever mechanism) Single Slider Crank Mechanism First Inversion Reciprocating engine or compressor. Second Inversion Whitworth quick return mechanism, Rotary I.C. engine (Gnome engine) etc. Third Inversion Slotted crank mechanism, Oscillatory engine. Fourth Inversion Hand pump, Pendulum pump or Bull engine. Double Slider Crank Mechanism Elliptical trammels.
