Applied Mechanics and Graphic Statics The following is not a law of static friction: The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction depends upon the roughness of the surface The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction depends upon the roughness of the surface ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact. If the coefficient of restitution is ½, the velocities of separation of the balls will be equal to Half the original velocity in the same direction Half the original velocity in the opposite direction Original velocity in the same direction Original velocity in the opposite direction Half the original velocity in the same direction Half the original velocity in the opposite direction Original velocity in the same direction Original velocity in the opposite direction ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A rope is wrapped twice around a rough pole with a coefficient of friction ‘A . It is subjected to a force Fj at one end and a gradually increasing force F2 is applied at the other end till the rope just starts slip-ping. At this instant the ratio of F2 to Fi is e2* 1 e*72 e4* e2* 1 e*72 e4* ANSWER DOWNLOAD EXAMIANS APP
