Applied Mechanics and Graphic Statics One end of an elastic string of natural length ‘l’ and modulus ‘X’ is kept fixed while to the other end is attached a particle of mass m which is hanging freely under gravity. The particle is pulled down vertically through a distance ‘x’, held at rest and then released.The motion is None of these A damped oscillatory motion A simple harmonic motion A rectilinear motion with constant speed None of these A damped oscillatory motion A simple harmonic motion A rectilinear motion with constant speed ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The following is not a law of static friction: The force of friction is dependent upon the area of contact The force of friction depends upon the roughness of the surface 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 is dependent upon the area of contact The force of friction depends upon the roughness of the surface 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
