Question

Match List-I with List-II.

List-I	List-II
A. Scotch-Russell Mechanism B. Geneva Mechanism C. Off-set slider crank mechanism D. Scotch yoke mechanism	I. Intermittent motion II. Quick return motion III. Simple harmonic motion IV. Straight line motion

• A. A-II, B-I, C-IV, D-III
• B. A-III, B-IV, C-II, D-I
• C. A-IV, B-I, C-II, D-III
• D. A-IV, B-III, C-I, D-II

Hint:

Geneva → intermittent, Scotch yoke → SHM, Offset crank → quick return.

Answer 1

The Correct Option is C

Concept: Different mechanisms produce characteristic motions:
• Straight-line motion
• Intermittent motion
• Quick return motion
• Simple harmonic motion (SHM)

Step 1: Scotch-Russell mechanism (A).

• Converts rotary motion into exact straight-line motion Thus: \[ A \rightarrow IV \]

Step 2: Geneva mechanism (B).

• Produces intermittent motion (start-stop movement) Thus: \[ B \rightarrow I \]

Step 3: Off-set slider crank (C).

• Produces quick return motion Thus: \[ C \rightarrow II \]

Step 4: Scotch yoke (D).

• Produces sinusoidal displacement → SHM Thus: \[ D \rightarrow III \]

Step 5: Final matching.
\[ A-IV,\; B-I,\; C-II,\; D-III \] \[ \boxed{\text{Answer: Option (3)}} \]
