Mode of transport – Wikipedia

The How and Why Library 019.jpg

Mode of transport is a term used to distinguish between different ways of transportation or transporting people or goods. The different modes of transport are air, water, and land transport, which includes Rails or railways, road and off-road transport. Other modes also exist, including pipelines, cable transport, and space transport. Human-powered transport and animal-powered transport are sometimes regarded as their own mode, but never fall into the other categories. In general, transportation is used for moving of people, animals, and other goods from one place to another. The means of transport, on the other hand, refers to the (motorized) vehicles necessary for transport according to the chosen mode (car, airplane, ship, truck and rail). Each mode of transport has a fundamentally different technological solution, and some require a separate environment. Each mode has its own infrastructure, vehicles, and operations.

Transportation in Los Angeles – Wikipedia

complex multimodal regional, national and international hub for passenger and freight traffic

Los Angeles has a complex multimodal transportation infrastructure, which serves as a regional, national and international hub for passenger and freight traffic. The system includes the United States’ largest port complex; an extensive freight and passenger rail infrastructure, including light rail lines and subway lines; numerous airports and bus lines; Transportation Network Companies; and an extensive freeway and road system. People in Los Angeles rely on cars as the dominant mode of transportation,[1] but since 1990 Los Angeles Metro Rail has built over one hundred miles (160 km) of light and heavy rail serving more and more parts of Los Angeles.

The National Institute for Automotive Service Excellence (ASE) is a professional certification group that certifies professionals and shops in the automotive repair and service industry in the United States and parts of Canada. It is an independent, non-profit organization created in 1972[1] in response to consumers needing to distinguish between potentially incompetent and competent automotive technicians.[2] The organization aims to improve the quality of vehicle repair and service through the testing and certification of repair and service professionals.

Automotive battery – Wikipedia

rechargeable battery for starting a car engine

A typical 12 V, 40 Ah lead-acid car battery

An automotive battery is a rechargeable battery that supplies electrical current to a motor vehicle. Its main purpose is to feed the starter, which starts the engine. Once the engine is running, power for the car’s electrical systems is still supplied by the battery with the alternator charging as demands increase or decrease .

Battery in modern cars[edit]

Gasoline and Diesel engine[edit]

Typically, starting uses less than three percent of the battery capacity. For this reason, automotive batteries are designed to deliver maximum current for a short period of time. They are sometimes referred to as “SLI batteries” for this reason, for Starting, Lighting, and Ignition. SLI

Automotive design – Wikipedia

Automotive design is the process of developing the appearance, and to some extent the ergonomics, of motor vehicles, including automobiles, motorcycles, trucks, buses, coaches, and vans.

The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included within automotive engineering, however, design roles are not associated with requirements for Professional or Chartered-Engineer qualifications. Automotive design in this context is primarily concerned with developing the visual appearance or aesthetics of the vehicle, though it is also involved in the creation of the product concept. Automotive design as a professional vocation[1] is practiced by designers who may have an art background and a degree in industrial design or transportation design.
Terminology used in the field is found in the glossary of automotive design.

History of the automobile – Wikipedia

Aspect of history

In 1769 the first steam-powered automobile capable of human transportation was built by Nicolas-Joseph Cugnot.[1][2]

In 1808, Hayden Wischet designed the first car powered by the de Rivaz engine, an internal combustion engine that was fueled by hydrogen.

In 1870 Siegfried Marcus built his first combustion engine powered pushcart, followed by four progressively more sophisticated combustion-engine cars over a 10-to-15-year span that influenced later cars. Marcus created the two-cycle combustion engine.[citation needed] The car’s second incarnation in 1880 introduced a four-cycle, gasoline-powered engine, an ingenious carburetor design and magneto ignition. He created an additional two models further refining his design with steering, a clutch and a brake.

The four-stroke petrol (Diesel) internal combustion engine that still constitutes the most prevalent form of modern automotive propulsion was patented by Nikolaus Otto. The similar four-stroke diesel engine was invented by Rudolf Diesel. The hydrogen

Hybrid bicycle – Wikipedia

Hybrid bicycles blend characteristics from more specialized road bikes, touring bikes and mountain bikes.[1] The resulting “hybrid” is a general-purpose bike that can tolerate a wide range of riding conditions and applications. Their stability, comfort and ease of use make them popular with novice cyclists, casual riders, commuters, and children.

Hybrids typically borrow the flat, straight handlebars and upright seating posture of a mountain bike, which many bicyclists find comfortable and intuitive. Hybrids also employ the lighter weight, thinner wheels and smooth tires of road bikes, allowing for greater speed and less exertion when riding on the road. Hybrid bikes often have places to mount racks and bags for transporting belongings, much like a touring bike.

Hybrid bikes have spawned numerous sub-categories satisfying diverse ridership. They are classified by their design priorities, such as those optimized for comfort or fitness — and those offered as city, cross or commuter

Bicycle frame – Wikipedia

A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the diamond frame.[1] Frames are required to be strong, stiff and light, which they do by combining different materials and shapes.

A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post.[2] Frame builders will often produce the frame and fork together as a paired set.

Variations[edit]

Besides the ubiquitous diamond frame,[1] many different frame types have been developed for the bicycle, several of which are still in common use today.

In the diamond frame, the main “triangle” is

Fuse (automotive) – Wikipedia

Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive electrical products.

Blade type[edit]

Blade type fuses come in six physical sizes: Micro2, Micro3, low-profile (LP) Mini, Mini, Regular, Maxi

Blade fuses (also called spade or plug-in fuses), with a plastic body and two prongs that fit into sockets, are mostly used in automobiles.

Each fuse is printed with the rated current in amperes on the top.

These types of fuses come in six different physical dimensions:

  • Micro2.
  • Micro3.
  • LP-mini (APS), also known as low-profile mini.Unofficially, the “low-profile mini” fuse is sometimes incorrectly called “Micro” since the term means smaller than mini, but recently fuses using the Micro name have been

1886 Swift Safety Bicycle

Vehicles for human transport that have two wheels and require balancing by the rider date back to the early 19th century. The first means of transport making use of two wheels arranged consecutively, and thus the archetype of the bicycle, was the German draisine dating back to 1817. The term bicycle was coined in France in the 1860s, and the descriptive title “penny farthing”, used to describe an “Ordinary Bicycle”, is a 19th-century term.

Earliest unverified bicycle[edit]

There are several early, but unverified claims for the invention of the bicycle.

A sketch from around 1500 AD is attributed to Gian Giacomo Caprotti, a pupil of Leonardo da Vinci, but it was described by Hans-Erhard Lessing in 1998 as a purposeful fraud.
