Correct answer: B
Working through it, option B is the one — generalised Hooke's law in 2-D links principal strains to principal stresses through E and ν — the σ₁ = E/(1−ν²)[ε₁ + νε₂] form matches option B, matching “σ₁ = E (ε₁ + νε₂) / (1 − ν²)”. Re-read the stem once before finalising — nearby options are often close distractors.

Straight to the answer: option D, elastic constants are linked by 1/E = 1/(3G) + 1/(9K) (equivalently forms relating E, G and K) — the printed choice that states that three-modulus relation is the correct pick, matching “E = 9KG / (3K + G)”. MPSC revisits this idea across RTO cycles, so lock the underlying relation, not just the letter.

The right pick is option A; for a gradually applied load the average force is half the peak, so strain energy stored is U = (σ²/2E)·V — that is σ²V/(2E), matching “σ²V / (2E)”. Underline the key noun in the stem, then eliminate options that name a related but different concept.

The verified answer here is option A: Mohr's circle radius equals maximum shear stress τ_max = √[((σ_x − σ_y)/2)² + τ_xy²], matching “√[((σx − σy)/2)² + τxy²]”. If two options look similar, check the definition word-for-word against the stem.

The examiner has marked option B, where a bar hanging under self-weight has linearly varying axial load, so average stress is half the bottom value — elongation δ = WL/(2AE), matching “WL / (2AE)”. A five-second sanity check against units, sign, or definition usually kills the distractors.
Read full explanation →Correct answer: C
You want option C on this one — points of contraflexure occur where bending moment crosses zero; on the given overhanging BMD that happens at sections C and D, matching “C and D”. Re-read the stem once before finalising — nearby options are often close distractors.
