Time Allowed : Three Hours

Maximum Marks : 300

INSTRUCTIONS Each question is printed both in Hindi and in English. Answers must be written in the medium specified in the Admission Certificate issued to you, which must be stated clearly on the cover of the answer-book in the space provided for the purpose. No marks will be given for the answers written in a medium other than that specified in the Admission Certificate. Candidates should attempt Question Nos. I and 5 which are compulsory, and any three of the remaining ques-tions selecting at least one question from each Section. The number of marks carried by each question is indicated at the end of the question. Symbols/notations carry their usual meanings, unless otherwise indicated. If any data is considered insufficient, assume suitable value and indicate the same clearly. Newton may be converted to kg using the equality 1 kilonewton (1 kN) = 100 kg, if found necessary. Neat sketches/diagrams may be drawn in the answer-book itself wherever required. Important : Whenever a Question is being attempted, all its parts/sub-parts must be attempted contiguously. This means that before moving on to the next Ques-tion to be attempted, candidates must finish attempting all parts /sub-pans of the previous Question attempted. This is to be strictly followed. Pages left blank in the answer-book are to be clearly struck out in ink. Any answers that follow pages left blank may not be given credit.

Section 'A'

1. (a) The critical buckling load of a cast iron hollow cylindrical column 3 m in length when hinged at both the ends is equal to P kN. When the column is fixed at both the ends, its critical load increases to (P + 300) kN. If the ratio of external diameter to internal diameter is 1.25 and E = 100 GPa, determine the external diameter of the column. 12
