Inversely proportional to Independent of Equal to Directly proportional to Inversely proportional to Independent of Equal to Directly proportional to ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The equation of motion for a vibrating system with viscous damping is (d²x/dt²) + (c/m). (dx/dt) + (s/m). x = 0. If the roots of this equation are real, then the system will be Over-damped Critically damped Under damped Without vibrations Over-damped Critically damped Under damped Without vibrations ANSWER DOWNLOAD EXAMIANS APP
