Question

Match List-I with List-II.

List-I	List-II
A. Toughness B. Endurance Strength C. Resistance to Abrasion D. Deflection in beam	I. Moment area method II. Hardness III. Energy absorbed before fracture IV. Fatigue loading

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

Hint:

Toughness → energy, Fatigue → endurance, Abrasion → hardness.

Answer 1

The Correct Option is C

Concept: Mechanical properties and methods:
• Toughness → energy absorption capacity
• Endurance strength → fatigue resistance
• Abrasion resistance → hardness
• Beam deflection → moment area method

Step 1: Toughness (A).

• Energy absorbed before fracture Thus: \[ A \rightarrow III \]

Step 2: Endurance strength (B).

• Resistance to fatigue loading Thus: \[ B \rightarrow IV \]

Step 3: Resistance to abrasion (C).

• Depends on hardness Thus: \[ C \rightarrow II \]

Step 4: Deflection in beam (D).

• Calculated using moment area method Thus: \[ D \rightarrow I \]

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