Theory of Machine Higher pairs are those which have Surface contact between the two elements when in motion Point or line contact between the two elements when in motion Elements of pairs not held together mechanically Two elements that permit relative motion Surface contact between the two elements when in motion Point or line contact between the two elements when in motion Elements of pairs not held together mechanically Two elements that permit relative motion ANSWER DOWNLOAD EXAMIANS APP
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 Lower pair Higher pair Force-closed pair Self-closed pair Lower pair Higher pair Force-closed pair Self-closed 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 Critically damped Without vibrations Under damped Over-damped Critically damped Without vibrations Under damped ANSWER DOWNLOAD EXAMIANS APP
