-
A simple lifting machine is self-locking (non-reversible), so the load does not run back when the effort is removed, if its efficiency is:
सही उत्तर: क) Less than 50%
A machine is reversible only if its efficiency exceeds 50%; a machine with efficiency below 50% is self-locking.

-
A lifting machine has a mechanical advantage of 40 and a velocity ratio of 50. Its efficiency is:
सही उत्तर: ख) 80%
Efficiency = MA/VR = 40/50 = 0.8, i.e. 80%.

For a perfectly plastic (perfectly inelastic) impact between two bodies, the coefficient of restitution is:
सही उत्तर: ख) 0
In a perfectly plastic impact the bodies move together after impact, so the relative velocity of separation is zero and e = 0; e = 1 is a perfectly elastic impact.

-
The centroid of a triangular area of height h is located at what distance from its base?
सही उत्तर: ग) h/3
The centroid lies at the intersection of the medians, which is one-third of the height above the base (two-thirds from the apex).

-
The centroid of a semicircular area of radius r lies on its axis of symmetry at what distance from the diameter?
सही उत्तर: घ) 4r/(3π)
For a semicircular lamina, ȳ = 4r/(3π) ≈ 0.424r from the straight edge; 2r/π applies to a semicircular arc (wire), not an area.

-
The principle that the moment of a force about any point equals the algebraic sum of the moments of its components about the same point is known as:
सही उत्तर: क) Varignon's theorem
Varignon's theorem (principle of moments) states that the moment of a resultant force about a point equals the sum of the moments of its components about that point.

The maternal mortality ratio is expressed as maternal deaths per:
सही उत्तर: क) 100,000 live births
The maternal mortality ratio is conventionally reported per 100,000 live births.

-
A body recovered after several weeks in a pond shows waxy, greasy, rancid-smelling transformation of the subcutaneous fat. This post-mortem change is:
सही उत्तर: घ) Adipocere formation
Adipocere forms by hydrolysis and hydrogenation of body fat in moist, warm conditions, such as submersion in water.

-
Itchy, purple, polygonal flat-topped papules on the wrists with fine white lines on their surface (Wickham's striae) indicate:
सही उत्तर: घ) Lichen planus
Lichen planus presents with the '6 Ps' (pruritic, purple, polygonal, planar papules and plaques) and Wickham's striae.

-
A patient taking an SSRI is given tramadol and develops agitation, fever, sweating, tremor, hyperreflexia and inducible clonus. The most likely diagnosis is:
सही उत्तर: ख) Serotonin syndrome
Combining serotonergic drugs can cause serotonin syndrome, whose hallmark is neuromuscular hyperactivity such as clonus and hyperreflexia.
