Kindly provide me the GATE mechanical engineering exam previous year paper……….

This is the GATE mechanical engineering exam previous year paper:

Q.13 Customers arrive at a ticket counter at a rate of 50 per hr and tickets are issued in the order of their
arrival. The average time taken for issuing a ticket is 1 min. Assuming that customer arrivals form a
Poisson process and service times are exponentially distributed, the average waiting time in queue
in min is
(A) 3 (B) 4 (C) 5 (D) 6

Q.14 In simple exponential smoothing forecasting, to give higher weightage to recent demand
information, the smoothing constant must be close to
(A) -1 (B) zero (C) 0.5 (D) 1.0

Q.15 A steel bar 200 mm in diameter is turned at a feed of 0.25 mm/rev with a depth of cut of 4 mm. The
rotational speed of the workpiece is 160 rpm. The material removal rate in mm3/s is
(A) 160 (B) 167.6 (C) 1600 (D) 1675.5

Q.16 A cube shaped casting solidifies in 5 min. The solidification time in min for a cube of the same
material, which is 8 times heavier than the original casting, will be
(A) 10 (B) 20 (C) 24 (D) 40

Q.17 For a ductile material, toughness is a measure of
(A) resistance to scratching (B) ability to absorb energy up to fracture
(C) ability to absorb energy till elastic limit (D) resistance to indentation

Q.18 In order to have maximum power from a Pelton turbine, the bucket speed must be
(A) equal to the jet speed. (B) equal to half of the jet speed.
(C) equal to twice the jet speed. (D) independent of the jet speed.
