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
Theory of Machine In a Hartnell governor, if a spring of greater stiffness is used, then the governor will be Unaffected of sensitivity Less sensitive More sensitive Isochronous Unaffected of sensitivity Less sensitive More sensitive Isochronous ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs) n = 3(l - 1) - 2j - h n = 2(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 3j - h n = 3(l - 1) - 2j - h n = 2(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 3j - h ANSWER DOWNLOAD EXAMIANS APP
