3. 農業機械 – Agricultural machinery is machinery used in farming or other agriculture. There are many types of equipment, from hand tools and power tools to tractors. Diverse arrays of equipment are used in organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an part of how the world is fed. With the coming of the Industrial Revolution and the development of complicated machines. Instead of harvesting grain by hand with a blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads, the first tractors appeared in the late 19th century. Power for agricultural machinery was supplied by ox or other domesticated animals. With the invention of power came the portable engine, and later the traction engine. Agricultural steam engines took over the heavy pulling work of oxen, the steam-powered machines were low-powered by todays standards but, because of their size and their low gear ratios, they could provide a large drawbar pull. Their slow speed led farmers to comment that tractors had two speeds, slow, and damn slow, the internal combustion engine, first the petrol engine, and later diesel engines, became the main source of power for the next generation of tractors. These engines also contributed to the development of the self-propelled, combined harvester and thresher, instead of cutting the grain stalks and transporting them to a stationary threshing machine, these combines cut, threshed, and separated the grain while moving continuously through the field. Combines might have taken the job away from tractors. They are used to push implements—machines that till the ground, plant seed, tillage implements prepare the soil for planting by loosening the soil and killing weeds or competing plants. The best-known is the plow, the ancient implement that was upgraded in 1838 by John Deere. Plows are now used frequently in the U. S. than formerly, with offset disks used instead to turn over the soil. The most common type of seeder is called a planter, and spaces seeds out equally in long rows, some crops are planted by drills, which put out much more seed in rows less than a foot apart, blanketing the field with crops. Transplanters automate the task of transplanting seedlings to the field, with the widespread use of plastic mulch, plastic mulch layers, transplanters, and seeders lay down long rows of plastic, and plant through them automatically

9. 車輪 – A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the components of the wheel. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, wheels are also used for other purposes, such as a ships wheel, steering wheel, potters wheel and flywheel. Common examples are found in transport applications, a wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, cognates within Indo-European include Icelandic hjól wheel, tyre, Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning circle or wheel. The invention of the falls into the late Neolithic. Note that this implies the passage of several wheel-less millennia even after the invention of agriculture and of pottery, precursors of wheels, known as tournettes or slow wheels, were known in the Middle East by the 5th millennium BCE. These were made of stone or clay and secured to the ground with a peg in the center, but required effort to turn. True potters wheels were apparently in use in Mesopotamia by 3500 BCE and possibly as early as 4000 BCE, and the oldest surviving example, which was found in Ur, dates to approximately 3100 BCE. The earliest well-dated depiction of a vehicle is on the Bronocice pot. The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia is now dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE. Two types of early Neolithic European wheel and axle are known, a type of wagon construction. They both are dated to c, in China, the wheel was certainly present with the adoption of the chariot in c.1200 BCE, although Barbieri-Low argues for earlier Chinese wheeled vehicles, c.2000 BC. In Britain, a wooden wheel, measuring about 1 m in diameter, was uncovered at the Must Farm site in East Anglia in 2016. The specimen, dating from 1, 100–800 years BCE, represents the most complete, the wheels hub is also present. A horses spine found nearby suggests the wheel may have part of a horse-drawn cart. The wheel was found in a settlement built on stilts over wetland and it is thought that the primary obstacle to large-scale development of the wheel in the Americas was the absence of domesticated large animals which could be used to pull wheeled carriages. The only large animal that was domesticated in the Western hemisphere, Nubians from after about 400 BCE used wheels for spinning pottery and as water wheels

2. 牽引自動車 – A trailer is generally an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials, sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities, where people can camp or stay have been referred to as trailers. In earlier days, many vehicles were towable trailers. In the United States, the term is used interchangeably with travel trailer and mobile home, varieties of trailers. Their origins lay in utility trailers built in a fashion to horse-drawn wagons. A trailer park is an area where homes are placed for habitation. In the United States trailers ranging in size from single-axle dollies to 6-axle,13 ft 6 in high,53 ft 0 in long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or 18-wheeler, enclosed toy trailers and motorcycle trailers can be towed by commonly accessible pickup truck or van, which generally require no special permit beyond a regular drivers license. Other trailers, such as utility trailers and travel trailers or campers come in single and multiple axle varieties, there also exist highly specialized trailers, such as genset trailers, pusher trailers and their ilk that are also used to power the towing vehicle. Others are custom-built to hold entire kitchens and other specialized equipment used by carnival vendors, there are also trailers for hauling boats. Popular campers use lightweight trailers, aerodynamic that can be towed by a small car and they are built to be lower than the tow vehicle, minimizing drag. Others range from two-axle campers that can be pulled by most mid-sized pickups to trailers that are as long as the host countrys law allows for drivers without special permits. Larger campers tend to be fully integrated recreational vehicles, which often are used to tow single-axle dolly trailers to allow the driver to bring small cars on their travels, a semi-trailer is a trailer without a front axle. A large proportion of its weight is supported either by a tractor or by a detachable front axle assembly known as a dolly. A semi-trailer is normally equipped with legs, called landing gear, which can be lowered to support it when it is uncoupled. In the United States, a single trailer cannot exceed a length of 57 ft 0 in on interstate highways, semi-trailers vary considerably in design, ranging from open-topped grain haulers through Tautliners to normal-looking but refrigerated 13 ft 6 in x 53 ft 0 in enclosures. Many semi-trailers are part of semi-trailer trucks, other types of semi-trailers include dry vans, flatbeds and chassis. A full trailer is a used in the United States for a freight trailer supported by front and rear axles

The Faraday disk was the first electric generator. The horseshoe-shaped magnet (A) created a magnetic field through the disk (D). When the disk was turned, this induced an electric current radially outward from the center toward the rim. The current flowed out through the sliding spring contact m, through the external circuit, and back into the center of the disk through the axle.
