 6.92. Tangent of angle of friction is equal to kinetic friction limiting friction angle of repose coefficient of friction friction force. ANSWER : : coefficient of friction Explanation :
 7.89. Coulomb friction is the friction between bodies having relative motion two dry surfaces two lubricated surfaces solids and liquids electrically charged particles. ANSWER : : bodies having relative motion Explanation :
 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. ANSWER : : angle between normal reaction and the resultant of normal reaction and the limiting friction Explanation :
 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. ANSWER : : ratio of limiting friction and normal reaction Explanation :
 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. ANSWER : : less Explanation :
