Re: Gate Previous Question Papers with Solutions for Mechanical
Mechanical Engineering GATE Examination Previous year Question Papers I am providing you the Gate Previous Question Papers for Mechanical. This question paper is as follows: Q.1 In abrasive jet machining, as the distance between the nozzle tip and the work surface increases, the material removal rate (A) increases continuously. (B) decreases continuously. (C) decreases, becomes stable and then increases. (D) increases, becomes stable and then decreases. Q.2 Match the following metal forming processes with their associated stresses in the workpiece. Metal forming process Type of stress 1. Coining P. Tensile 2. Wire Drawing Q. Shear 3. Blanking R. Tensile and compressive 4. Deep Drawing S. Compressive (A) 1-S, 2-P, 3-Q, 4-R (B) 1-S, 2-P, 3-R, 4-Q (C) 1-P, 2-Q, 3-S, 4-R (D) 1-P, 2-R, 3-Q, 4-S Q.3 In an interchangeable assembly, shafts of size 010 . 0 040 . 0 000 . 25 mm mate with holes of size 020 . 0 030 . 0 000 . 25 mm. The maximum interference (in microns) in the assembly is (A) 40 (B) 30 (C) 20 (D) 10 Q.4 During normalizing process of steel, the specimen is heated (A) between the upper and lower critical temperature and cooled in still air. (B) above the upper critical temperature and cooled in furnace. (C) above the upper critical temperature and cooled in still air. (D) between the upper and lower critical temperature and cooled in furnace. Q.5 Oil flows through a 200 mm diameter horizontal cast iron pipe (friction factor, f = 0.0225) of length 500 m. The volumetric flow rate is 0.2 m3/s. The head loss (in m) due to friction is (assume g = 9.81 m/s2) (A) 116.18 (B) 0.116 (C) 18.22 (D) 232.36 For more questions paper are providing you the attachment PDF file.
