Step-by-step solution
- Match Derrick with Steel work (a – 3) - Match Claw-hammer with Wood work (b – 2) - Match Chain-Lewis with Stone masonry work (c – 1) - Match Drop-hammer with Pile foundation (d – 5) - Choose option d corresponding to code a – 3, b – 2, c – 1, d – 5
Explanation
Option d is correct because each tool matches its specific application: a Derrick (a crane-like lifting device) is used in steel work for hoisting heavy beams; a Claw-hammer is a standard tool used in wood work for driving and removing nails; a Chain-Lewis is a lifting device inserted into stones for stone masonry work; and a Drop-hammer is a heavy weight dropped to drive piles into the ground for a pile foundation.
Shortcut
Use simple word associations: - Claw-hammer: Wood (standard carpentry tool for nails) - Drop-hammer: Pile foundation (dropped to drive piles into ground) - Chain-Lewis: Stone (Lewis pins lift heavy stones) - Derrick: Steel (heavy crane used in structural steelwork)
Common mistake
A common mistake is confusing Chain-Lewis with pile foundation equipment or concrete compaction tools, or confusing Drop-hammer with concrete compaction rather than pile driving.
Correct answer: D) a – 3, b – 2, c – 1, d – 5
