-
A steel bar 2 m long with cross-sectional area 500 mm² carries an axial tensile load of 100 kN. If E = 200 GPa, its elongation is:
सही उत्तर: ख) 2 mm
δ = PL/(AE) = (100,000 × 2000)/(500 × 200,000) = 2 mm.

A uniform bar of length L, unit weight γ and modulus E hangs vertically from its top end. Its elongation due to its own weight is:
सही उत्तर: ख) γL²/(2E)
Axial force varies linearly from zero at the bottom to γAL at the top, so the elongation is half that of a full end load: γL²/(2E).

The elastic section modulus of a solid circular section of diameter d is:
सही उत्तर: घ) πd³/32
Z = I/ymax = (πd⁴/64)/(d/2) = πd³/32.

-
The moment of inertia of a hollow circular section with external diameter D and internal diameter d about a diameter is:
सही उत्तर: क) π(D⁴ − d⁴)/64
The I of a solid circle about a diameter is πD⁴/64, so for the hollow section it is π(D⁴ − d⁴)/64 (π/32 would be the polar moment).

-
The moment of inertia of a triangular section of base b and height h about its centroidal axis parallel to the base is:
सही उत्तर: ग) bh³/36
For a triangle, I about the base is bh³/12; transferring to the centroid (h/3 from the base) gives bh³/12 − (bh/2)(h/3)² = bh³/36.

Frostbitten fingers should be rewarmed by immersion in water at about:
सही उत्तर: ख) 37 to 39 °C
Rapid rewarming in circulating water at about 37-39 °C is recommended; hotter water risks burns of numb tissue.

-
Which drug is used for the prevention and treatment of high-altitude pulmonary oedema (HAPE)?
सही उत्तर: ग) Nifedipine
Nifedipine lowers pulmonary artery pressure and is used to prevent and treat HAPE, along with descent and oxygen.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The single most important treatment for high-altitude cerebral or pulmonary oedema is:
सही उत्तर: ग) Immediate descent to a lower altitude
Descent is the definitive treatment; oxygen, dexamethasone (for cerebral oedema) and nifedipine (for pulmonary oedema) are adjuncts.

-
The drug commonly used for prevention of acute mountain sickness in trekkers ascending rapidly in the Himalayas is:
सही उत्तर: ग) Acetazolamide
Acetazolamide, a carbonic anhydrase inhibitor, speeds acclimatisation by causing a mild metabolic acidosis that stimulates breathing.

-
In adult cardiac arrest, the recommended dose of adrenaline (epinephrine) intravenously is:
सही उत्तर: घ) 1 mg every 3 to 5 minutes
Current guidelines recommend 1 mg IV/IO adrenaline (10 mL of 1:10,000) every 3-5 minutes during CPR.
