Figure-out the odd point in the following (a) Proportinal limit (b) Elastic limit (c) Yeild point (d) Fracture point ANS: D 3. If a material is subjected to two incremental true strains namely ε1 and ε2, then the total true strain is (a) ε1 * ε2 (b) ε1 - ε2 (c) ε1 + ε2 (d) ε1 / ε2 ANS: C 4. Engineering stress-strain curve and True stress-strain curve are equal up to (a) Proportional limit (b) Elastic limit c) Yeild point (d) Tensile strength point ANS:C 5. Value of Poisson’s ratio for ionic solids in the range of (a) 0.1 (b) 0.2 (c) 0.3 (d) 0.4 ANS:B 6.

Re: ONGC GT Petroleum engineering question paper
Hi, I have appear in GT for Petroleum branch in 2014 and I can remember easily that these are not the question which has been asked.Might be they are belong some other stream. Question has been asked from reservoir and production facility with some question from shale and cbm. Just focus on basic. Regards Vikash Quote:
