Question

What is the correct sequence of inversion of a Slider crank chain from first inversion to fourth inversion? A. Rotary Engine
B. Reciprocating Engine
C. Oscillating Cylinder Engine
D. Hand pump

• A. A, C, B, D
• B. B, A, C, D
• C. A, B, C, D
• D. B, C, A, D

Hint:

Remember: First inversion of slider crank → Reciprocating engine (most common).

Answer 1

The Correct Option is D

Concept: A slider-crank mechanism gives different inversions depending on which link is fixed.

Step 1: Understand inversion concept.
Inversion is obtained by fixing different links of a kinematic chain.

Step 2: First inversion (link 1 fixed).

• Gives Reciprocating Engine mechanism
• Common in IC engines Thus: First inversion → B

Step 3: Second inversion (link 2 fixed).

• Produces Oscillating Cylinder Engine Thus: Second inversion → C

Step 4: Third inversion (link 3 fixed).

• Produces Rotary Engine Thus: Third inversion → A

Step 5: Fourth inversion (link 4 fixed).

• Produces Hand pump mechanism Thus: Fourth inversion → D

Step 6: Final sequence.
\[ B \rightarrow C \rightarrow A \rightarrow D \] Final Answer: \[ \boxed{B, C, A, D} \]
