TheFormula Grants for Rural Areas program provides capital, planning, and operating assistance to states to support public transportation in rural areas with populations of less than 50,000, where many residents often rely on public transit to reach their destinations. The program also provides funding for state and national training and technical assistance through the Rural Transportation Assistance Program.
Eligible recipients include states and federally recognized Indian Tribes. Subrecipients may include state or local government authorities, nonprofit organizations, and operators of public transportation or intercity bus service.
The federal share is 80 percent for capital projects, 50 percent for operating assistance, and 80 percent for Americans with Disabilities Act (ADA) non-fixed route paratransit service. Section 5311 funds are available to the States during the fiscal year of apportionment plus two additional years (total of three years). Funds are apportioned to States based on a legislative formula that includes land area, population, revenue vehicle miles, and low-income individuals in rural areas.
Each state must spend no less than 15 percent of its annual apportionment for the development and support of intercity bus transportation, unless it can certify, after consultation with intercity bus service providers, that the intercity bus needs of the state are being adequately met.
FTA has published a Dear Colleague letter stating that intercity bus providers that use a nationwide allocation model to allocate costs are eligible to be reimbursed for net operating costs under Section 5311(f), including funding provided by supplemental COVID programs such as the Coronavirus Aid, Relief, and Economic Security (CARES) Act, the Coronavirus Response and Relief Supplemental Appropriations Act of 2021 (CRRSAA), and the American Rescue Plan Act of 2021.
The Transportation Technical Assistance Coordination Library (TACL) provides a sustainable methodology and platform to access resources across a diverse range of transportation technical assistance centers and FTA. Participating FTA-funded technical assistance centers include:
In March 2022, FTA posted guidance clarifying coordination on human services transportation on a new transportation coordination webpage. Coordinated transportation involves multiple entities working together to deliver one or more components of a transportation service to increase capacity. The transportation coordination guidance aims to reduce overlap between the 130 CCAM programs across nine agencies that may fund human services transportation and incentivize collaboration by clarifying eligible reporting into the National Transit Database (NTD). This new guidance addresses the following topics as they relate to NTD reporting: definition of public transportation; paratransit; charter service; incidental use of transit assets; and trip brokering.
In science, a formula is a concise way of expressing information symbolically, as in a mathematical formula or a chemical formula. The informal use of the term formula in science refers to the general construct of a relationship between given quantities.
In mathematics, a formula generally refers to an equation relating one mathematical expression to another, with the most important ones being mathematical theorems. For example, determining the volume of a sphere requires a significant amount of integral calculus or its geometrical analogue, the method of exhaustion.[3] However, having done this once in terms of some parameter (the radius for example), mathematicians have produced a formula to describe the volume of a sphere in terms of its radius:
Having obtained this result, the volume of any sphere can be computed as long as its radius is known. Here, notice that the volume V and the radius r are expressed as single letters instead of words or phrases. This convention, while less important in a relatively simple formula, means that mathematicians can more quickly manipulate formulas which are larger and more complex.[4] Mathematical formulas are often algebraic, analytical or in closed form.[5]
In a general context, formulas often represent mathematical models of real world phenomena, and as such can be used to provide solutions (or approximate solutions) to real world problems, with some being more general than others. For example, the formula
is an expression of Newton's second law, and is applicable to a wide range of physical situations. Other formulas, such as the use of the equation of a sine curve to model the movement of the tides in a bay, may be created to solve a particular problem. In all cases, however, formulas form the basis for calculations.
In mathematical logic, a formula (often referred to as a well-formed formula) is an entity constructed using the symbols and formation rules of a given logical language.[7] For example, in first-order logic,
When the chemical compound of the formula consists of simple molecules, chemical formulas often employ ways to suggest the structure of the molecule. There are several types of these formulas, including molecular formulas and condensed formulas. A molecular formula enumerates the number of atoms to reflect those in the molecule, so that the molecular formula for glucose is C6H12O6 rather than the glucose empirical formula, which is CH2O. Except for the very simple substances, molecular chemical formulas generally lack needed structural information, and might even be ambiguous in occasions.
In computing, a formula typically describes a calculation, such as addition, to be performed on one or more variables. A formula is often implicitly provided in the form of a computer instruction such as.
Formulas used in science almost always require a choice of units.[11] Formulas are used to express relationships between various quantities, such as temperature, mass, or charge in physics; supply, profit, or demand in economics; or a wide range of other quantities in other disciplines.
An example of a formula used in science is Boltzmann's entropy formula. In statistical thermodynamics, it is a probability equation relating the entropy S of an ideal gas to the quantity W, which is the number of microstates corresponding to a given macrostate:
Formula One, commonly known as Formula 1 or F1, is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fdration Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been one of the world's premier forms of racing since its inaugural running in 1950. The word formula in the name refers to the set of rules all participants' cars must follow. A Formula One season consists of a series of races, known as Grands Prix. Grands Prix take place in multiple countries and continents on either purpose-built circuits or closed public roads.
A point-system is used at Grands Prix to determine two annual World Championships: one for the drivers, and one for the constructors (the teams). Each driver must hold a valid Super Licence, the highest class of racing licence the FIA issues, and the races must be held on grade one tracks, the highest grade rating the FIA issues for tracks.
Formula One cars are the world's fastest regulated road-course racing cars, owing to very high cornering speeds achieved by generating large amounts of aerodynamic downforce. Much of this downforce is generated by front and rear wings, which have the side effect of causing severe turbulence behind each car. The turbulence reduces the downforce the cars following directly behind generate, making it hard to overtake. Major changes made to the cars for the 2022 season (and later for the 2026 season) have resulted in greater use of ground effect aerodynamics and modified wings to reduce the turbulence behind the cars, with the goal of making overtaking easier.[1] The cars depend on electronics, aerodynamics, suspension, and tyres. Traction control, launch control, and automatic shifting, and other electronic driving aids were first banned in 1994. They were briefly reintroduced in 2001, and have more recently been banned since 2004 and 2008, respectively.[2]
The first world championship race, the 1950 British Grand Prix, took place at Silverstone Circuit in the United Kingdom on 13 May 1950.[6] Giuseppe Farina, competing for Alfa Romeo, won the first Drivers' World Championship, narrowly defeating his teammate Juan Manuel Fangio. Fangio won the championship in 1951, 1954, 1955, 1956, and 1957.[7] This set the record for the most World Championships won by a single driver, a record that stood for 46 years until Michael Schumacher won his sixth championship in 2003.[7]
This era featured teams managed by road-car manufacturers, such as Alfa Romeo, Ferrari, Mercedes-Benz and Maserati. The first seasons featured prewar cars like Alfa Romeo's 158, which were front-engined, with narrow tyres and 1.5-litre supercharged or 4.5-litre naturally aspirated engines. The 1952 and 1953 seasons were run to Formula Two regulations, for smaller, less powerful cars, due to concerns over the dearth of Formula One cars.[13][14] When a new Formula One formula for engines limited to 2.5 litres was reinstated for the 1954 world championship, Mercedes-Benz introduced its W196, which featured things never seen on Formula One cars before, such as desmodromic valves, fuel injection, and enclosed streamlined bodywork. Mercedes drivers won the championship for the next two years, before the team withdrew from all motorsport competitions due to the 1955 Le Mans disaster.[15]
The first major technological development in the sport was Bugatti's introduction of mid-engined cars. Jack Brabham, the world champion in 1959, 1960, and 1966, soon proved the mid-engine's superiority over all other engine positions. By 1961 all teams had switched to mid-engined cars. The Ferguson P99, a four-wheel drive design, was the last front-engined Formula One car to enter a world championship race. It entered the 1961 British Grand Prix, the only front-engined car to compete that year.[16]
