Q.13 Customers arrive at a ticket counter at a rate of 50 per hr and tickets are issued in the order of their

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

(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.

Q.19 Consider one-dimensional steady state heat conduction along x-axis (0 ≤ x ≤ L), through a plane
wall with the boundary surfaces (x=0 and x=L) maintained at temperatures of 0°C and 100°C. Heat
is generated uniformly throughout the wall. Choose the CORRECT statement.
(A) The direction of heat transfer will be from the surface at 100°C to the surface at 0°C.
(B) The maximum temperature inside the wall must be greater than 100°C.
(C) The temperature distribution is linear within the wall.
(D) The temperature distribution is symmetric about the mid-plane of the wall.
