Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

21.76. Frictional force encountered after commencement of motion is called

post friction
limiting friction
kinematic friction
frictional resistance
dynamic friction.

22.88. Limiting force of friction is the

tangent of angle between normal-reac-tion and the resultant of normal reac-tion and limiting friction
ratio of limiting friction and normal reaction
the friction force acting when the body is just about to move
the friction force acting when the body is in motion
minimum force of friction.

23.74. On the ladder resting on the ground and leaning against a smooth vertical wall, the force of friction will be

downwards at its upper end
upwards at its upper end
perpendicular to the wall at its upper end
zero at its upper end
none of the above.

24.69. The coefficient of friction depends on

area of contact
shape of surfaces
strength of surfaces
nature of surface
all of the above.
