Applied Mechanics and Graphic Statics It is observed that in a certain sinusoidal oscillation, the amplitude is linearly dependent on the frequency f. If the maximum velocity during the oscillation is V, then V must be proportional to 1/f f² 1/f² f 1/f f² 1/f² f ANSWER DOWNLOAD EXAMIANS APP
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 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 ANSWER DOWNLOAD EXAMIANS APP
