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 ...

Circular motion is easy to produce using any sort of wheel device. However, true linear or straight line motion is not. To create linear motion, the circular motion of a crankshaft needs to be ...

A cam is a simple mechanism that converts rotary motion (movement that goes round in a circle) into linear motion (movement in a straight line). These mechanisms can be found in car engines ...
