A cc slab of thickness 20 cm is constructed over a base of granular material with a modulus of reaction 10 kg/cm3. The maximum temperature differential between the top and bottom of the slab is found to be 19°C during summer day and night. The spacing between transverse joints is 8 m and the spacing between longitudinal joints is 4 m. The design wheel load is 5100 kg, radius of contact area is 15 cm, Poisson’s ratio is 0.15, modulus of elasticity is 3×105 kg/cm2, the thermal coefficient is 10 ×10-6 /°C and the coefficient of friction is 1.5. Using the above information, find the worst combination of stresses at the edge of the pavement.
The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1: It would be possible to adduce many examples showing what could be done with the limited means' at our ancestor’s disposal in the way of making life comfortable. S6: I hope, in this essay, to make that connection manifest. P: What have comfort and cleanliness to do with politics, morals, and religion? Q: But look more closely and you will discover that there exists the closest connection between the recent growth of comfort and the recent history of ideas. R: They show that if they lived in filth and discomfort, it was because filth and discomfort fitted in with their principles, political, moral and religious. S: At a first glance one would say that there could be no causal connection between arm chairs and democracies, sofas and the family system, hot baths and religious orthodoxy. The correct sequence should be
The growth rate of pearlite, v, and the interlamellar spacing S are given by the following relation, $$v = k.\frac{1}{S}\left( {\frac{{1 - {S_c}}}{S}} \right)$$    where Sc is the critical spacing at which the growth rate is zero and k is a materials constant. The actual interlamellar spacing observed will correspond to
