When a wire is pulled it lengthens and at the same time grows thinner, and Poisson's ratio records how large the sideways contraction is compared with the lengthwise extension; it is a pure number, with theoretical limits of minus one and one half and practical values of about 0.2 to…

Elasticity in physics is not the ability to stretch far but the strength of the restoring tendency, measured by the stress needed to produce a given strain, and steel demands an enormously greater stress than rubber for the same fractional extension.

The bulk modulus measures how strongly a substance resists a change in volume under uniform pressure, so its reciprocal measures how readily the volume yields, and that quantity is called compressibility.

It governs the stretching or compression of a wire or rod along its length and is obtained by dividing the force per unit area of cross section by the fractional change in length.

Strain is defined as the change in a dimension divided by the original value of the same dimension, a length divided by a length or a volume divided by a volume, so the units cancel and only a pure number survives.

Stress is the restoring force divided by the area over which it acts, so its unit is the newton per square metre, and that combination is given the special name pascal, the same unit used for pressure.

Hooke found that so long as a body is not strained beyond its elastic limit, the restoring force per unit area rises in step with the fractional deformation, and the constant ratio of the two is called the modulus of elasticity.

The academy for the Rajasthani language, its literature and culture works from Bikaner, publishing works in Rajasthani and honouring writers in the language.

The correct answer is B, Vijaydan Detha, often called Bijji, who spent his life at Borunda in Jodhpur district gathering the oral tales of the countryside and retelling them in Rajasthani in the many volumes of Bataan Ri Phulwari; several of his stories became well known Hindi films.

Nainsi was the minister of Maharaja Jaswant Singh of Marwar in the seventeenth century, and besides the Nainsi Ri Khyat he compiled this district by district record of the parganas of Marwar, with details of villages, revenue and families, which is why he is called the Abul Fazl of Rajasthan…

He served the Bundi court in the nineteenth century and wrote the Vansh Bhaskar, a long chronicle of the Hada rulers in verse, and the Veer Satsai, seven hundred couplets of martial feeling that were widely recited in the period of the revolt of 1857.

The correct answer is A, Chand Bardai, who is remembered as the court poet of Prithviraj Chauhan and the author of the Prithviraj Raso, the long martial epic that made the Rasau form famous, although historians treat many of its details and dates with caution because the text grew by…

The correct answer is B, Prithviraj Rathore, a prince of the Bikaner house known in tradition as Peethal, who told the story of Krishna and Rukmini in Dingal verse; the poem is counted among the finest works in the language and is the one most often cited as a Dingal…

Dingal is the literary style built on Marwari, and the Charans used it for heroic verse on battle, honour and self sacrifice, sung in a loud rolling metre; the Veli Krisan Rukmani Ri of Prithviraj Rathore is a celebrated example.

It is the speech of Jodhpur, Pali, Nagaur, Barmer and Jalore, that is of the largest region of the state, and the Dingal poetry of the Charan poets was composed in it; its speakers also carried it across India with the trading communities of Marwar.

These four districts of the south east formed the Hada Chauhan country, from which the region takes the name Hadoti and the dialect its name Hadoti or Harauti.

The tract formed by these two districts in the far south of Rajasthan is called Wagad, and the Bhil population there speaks Wagdi, which carries features of both Rajasthani and Gujarati because of its position on the border.

In his Linguistic Survey of India he used the name Rajasthani in 1912 for the group of speeches of this region and classified its dialects, replacing older names such as Maru Bhasha and Maru Gurjar.

Article 13(1) makes a pre-Constitution law void only to the extent of its inconsistency with the Fundamental Rights, so the Supreme Court in Bhikaji Narain Dhakras, 1955, held that such a law is not erased but merely eclipsed, staying unenforceable until the shadow is lifted, after which it revives.

An eleven judge bench held by six to five that Parliament cannot abridge Fundamental Rights by amendment, but the Court did not want to unsettle the land reform amendments already acted upon, so it declared that its ruling would operate only for the future.
