Here I am sharing the last year question paper of GATE Mechanical Engineering Exam?

The following are the data for two crossed helical gears used for speed reduction:
Gear I : Pitch circle diameter in the plane of rotation 80 mm and helix angle 30º
Gear II : Pitch circle diameter in the plane of rotation 120 mm and helix angle 22.5º
If the input speed is 1440 rpm, the output speed in rpm is
(A) 1200 (B) 900 (C) 875 (D) 720

A thin walled spherical shell is subjected to an internal pressure. If the radius of the shell is increased by 1% and the thickness is reduced by 1%, with the internal pressure remaining the same, the percentage change in the circumferential (hoop) stress is
(A) 0 (B) 1 (C) 1.08 (D) 2.02

The area enclosed between the straight line y = x and the parabola y = x2 in the x-y plane is
(A) 1/6 (B) 1/4 (C) 1/3 (D) 1/2

Which one of the following is NOT a decision taken during the aggregate production planning stage?
(A) Scheduling of machines (B) Amount of labour to be committed
(C) Rate at which production should happen (D) Inventory to be carried forward
