Where, as in the case of the crank and pitman, a rectilinear motion and circular motion are coupled, there may be a loss in the application of the power to useful work, always consequent upon the ...

Motion: An object is said to be in motion if its position changes with time”. Rectilinear motion: A particle moving along a straight-line is said to undergo rectilinear motion. For example ...
