Applied Mechanics and Graphic Statics The following is not a law of static friction: 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 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 stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 40 m/sec 25 m/sec 50 m/sec 15 m/sec 40 m/sec 25 m/sec 50 m/sec 15 m/sec ANSWER DOWNLOAD EXAMIANS APP
