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 depends upon the roughness of the surface 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 magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction depends upon the roughness of the surface 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 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 30 m/sec 50 m/sec 20 m/sec 40 m/sec 30 m/sec 50 m/sec 20 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
