Theory of Machine When the two elements of a pair have a surface contact when relative motion takes place and the surface of one element slides over the surface of the other, the pair formed is known as a Self-closed pair Lower pair Force-closed pair Higher pair Self-closed pair Lower pair Force-closed pair Higher pair 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 Under damped Critically damped Without vibrations Over-damped Under damped Critically damped Without vibrations ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine Relationship between the number of links (L) and number of pairs (P) is P = 2L - 2 P = 2L + 2 P = 2L + 4 P = 2L - 4 P = 2L - 2 P = 2L + 2 P = 2L + 4 P = 2L - 4 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The inversion of a mechanism is Changing of a higher pair to a lower pair Obtained by fixing different links in a kinematic chain Turning its upside down Obtained by reversing the input and output motion Changing of a higher pair to a lower pair Obtained by fixing different links in a kinematic chain Turning its upside down Obtained by reversing the input and output motion ANSWER DOWNLOAD EXAMIANS APP
