Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2014 and IES 2014 examinations :

6.92. Tangent of angle of friction is equal to

kinetic friction
limiting friction
angle of repose
coefficient of friction
friction force.

7.89. Coulomb friction is the friction between

bodies having relative motion
two dry surfaces
two lubricated surfaces
solids and liquids
electrically charged particles.

8.68. Angle oT friction is the

angle between normal reaction and the resultant of normal reaction and the limiting friction
ratio of limiting friction and normal reaction
he ratio of minimum friction force to the friction force acting when the body is just about to move
the ratio of minimum friction force to friction force acting when the body is in motion
ratio of static and dynamic friction.

9.77. Coefficient of friction is the

angle between normal reaction and the resultant of normal reaction and the 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
tangent of angle of repose.

10.90. Dynamic friction as compared to static friction is

same
more
less
may be less of more depending on na-ture of surfaces and velocity
has no correlation.
