They do this by shaking the pile of fasteners in a specific way — a spiral motion which encourages them to work to the edge of the pile and align themselves on a spiral track which leads to a ...

This spiral motion allows scientists to detect even tiny changes in electron behavior. “The key idea behind this approach is ...

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 ...

Save guides, add subjects and pick up where you left off with your BBC account. A cam is a simple mechanism that converts rotary motion (movement that goes round in a circle) into linear motion ...
