GATE Mechanical Branch paper with solutions
I am doing preparation for the GATE Mechanical Branch paper? So I am searching for the GATE Mechanical Branch paper? Can you please provide me this? You are searching for the GATE Mechanical Branch paper. Here I am uploading a file that contains the GATE Mechanical Branch paper. You can download this from here. 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 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. 4 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 GATE Mechanical Branch paper more papers detail to attched pdf files......................
