A Layshaft in a watermill is a horizontal shaft, carrying a Wallower and one or more Spur Wheels. The term can also refer to a minor shaft driving machinery by pulleys and belts. Overdrift Millstones driven from above are known as Overdrift stones. Pit Wheel The Pit Wheel is mounted on the opposite end of the axle to the waterwheel.
Carrying 675 US gallons (2,560 L; 562 imp gal) of water, the traction engine weighed 48,000 pounds (22,000 kg) and rode on huge metal wheels. Holt's tractors were popular despite their weight and awkward size because they could harvest large fields for one-sixth the cost of a horse-drawn combine. [18]
The foreground shows the mandrel for the base. Behind the finished vase are the spinning tools used to shape the metal. Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part.

Protrusions molded into rubber tractor tire treads are known as lugs, as are cleats for round wheels, [citation needed] which perform a similar function. Unlike metal grousers, these rubber tire treads or crawler-track shoes/pads may be more suitable for driving on roads. [7] Grousers on a captured World War I British tank.
Steel tire on a steam locomotive's driving wheel is heated with gas flames to expand and loosen it so it may be slipped over the wheel.. The steel wheel of a steam locomotive and other older types of rolling stock were usually fitted with a steel tire (American English) or tyre (in British English, Australian English and others) to provide a replaceable wearing element on a costly wheel.
Turning the steering wheel displaced the bogies to the left or right inducing a modest turn. Further turning of the wheel engaged braking on one side or the other. The Light Tank Mk VII Tetrarch used a similar system but the front wheels and two middle wheels on either side pivoted to induce the warp. [7]
