Applied Mechanics and Graphic Statics The following is not a law of static friction: The force of friction always acts in a direction opposite to that in which the body tends to move The force of friction is dependent upon the area of contact 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 always acts in a direction opposite to that in which the body tends to move The force of friction is dependent upon the area of contact 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 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is 4/5 3/5 3/4 5/3 4/5 3/5 3/4 5/3 ANSWER DOWNLOAD EXAMIANS APP
