The Graduate Aptitude Test in Engineering (GATE) is an all-India examination that primarily tests the comprehensive understanding of various undergraduate subjects in engineering and science. This exam was National Coordination Board for taking admission for the master degree program in Indian colleges

As you want question paper of gate for mechanical department here I am providing you for the same

Q The basic load rating of a ball bearing is

(a) the maximum static radial load that can be applied without causing any
plastic deformation of bearing component.
(b) the radial load at which 90% of the group of apparently identical bearings
run for one million revolutions before the first evidence of failure.
(c) the maximum radial load that can be applied during operation without any
plastic deformation of bearing components.
(d) a combination of radial and axial loads that can be applied without any
plastic deformation.
