As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver it to the reciprocating pump, the suction and discharge takes place.
A wedge(the blade) and a gear ( what turns the blade)
Shearing requires one blade to pass over another blade or a fixed edge. Cutting only requires one blade.
The farm tool with a curved blade used for cutting grain is called a sickle. It features a sharp, curved edge that allows for efficient harvesting of crops like wheat and barley. Historically, sickles have been essential for agricultural practices before the advent of modern machinery. Their design enables users to cut through stalks with a sweeping motion.
The average size of a windmill blade ranges from 35 to 45 meters (115 to 148 feet) in length.
A windmill on a map is typically represented by a small icon that resembles a propeller or rotor blade structure mounted atop a tower. It can vary in design, but it usually signifies a location where wind energy is being harnessed.
It's called "blade" or a "sail".
vane - Any of several usually relatively thin, rigid, flat, or sometimes curved surfaces radially mounted along an axis, as a blade in a turbine or a sail on a windmill, that is turned by or used to turn a fluid.

A windmill turns because the blades face into the wind and are pitched (twisted) so that the air passing onto the blades pushes the blade around the pivot point. If the blade is pitched one way, the windmill will turn to CCW. If they are pitched the other way, it will turn CW.= There may be a convention or tradition or popular design in Ireland that pitches the blades so it turns CW.=
In theory the less blades you use on a windmill the faster it's top speed will be. There have been one bladed designs in the past that have worked, they just never really caught on. Not to mention a one bladed design is harder to start up in light winds. Hope this helps.
Technically, it is. Each blade is a lever, with the axle being the fulcrum of each lever.
Bulldozers are not used for lifting objects. They push dirt, rocks, debris, etc. with a large blade or do other tasks involving pushing or pulling.
