Can Land Rover 300tdi wheels fit Land Rover discovery 2?
No the wheels have a different stud pattern. the disco 2 studs are closer to gether. you can buy stud pattern changers for any landrover store eg. landranger middlwhich
What is the elevation difference between one contour line and the next?
The height between contours is usually stated in the map's legend. For instance, on an Ordnance Survey (UK) 1:50 000 Landranger Series, contours are at 10 metres vertical interval.
How do you identify landforms on a ordnance survey map?
On the OS Explorer series (Scale 1:25,000) of Ordnance Survey maps, a well is denoted as a small unfilled blue circle with a blue capital "W" next to it. Springs are denoted by the same circle however the letters "Spr" are used in place of "W".The smaller scale maps (i.e. showing a larger area) such as the OS Landranger series (Scale 1:50,000) do not appear detailed enough to display wells (and they do not appear in the Key).See related links.
A scale written as a ratio in simplest form?
Convert the units of both sides to the same, then remove the units and simplify (if possible by dividing both sides by a common divisor greater than 1). eg The Landranger series map scale of 2 cm equals 1 km: 1 m = 100 cm 1 km = 1,000 m → 1 km = 1,000 x 100 cm = 100,000 cm 2 cm : 1 km → 2 cm : 1 x 100,000 cm → 2 cm : 100,000 cm → 2 : 100,000 → 1 : 50,000
What is the importance of the mathematical understanding of Ratios in real life?
Ratios are used in scale plans. For example an architect will draw a scale plan of an extension in a ratio of, say 1:20 which means that every 1 m on the plan is equal to 20 m in real life. Another, more commonly used area of scale plans is in maps. Common scales are 1:50,000 (Landranger series from OS, 1 cm on map = 0.5 km on the ground), and 1:25,000 (Pathfinder series1 cm on map = 0.25 km on the ground). The Landranger series of maps was originally derived from the old 1:63360 scale maps which was 1 inch = 1 mile map. Ratios are also used in cookery. For example a Sponge mix (for 2 x 6" tins) is given as 3 eggs, 6 oz fat (margarine), 6 oz flour, 6 oz sugar. However, with different sized tins, different amounts of each will be used, as long as the ratio of eggs : fat : flour : sugar remains the same (at 1 : 2 : 2 : 2). [The number of eggs actually depends upon the size (and hence weight) of the eggs, which for the recipe assumes 1 egg weighs (near enough) 2 oz - my mum taught me to weight the 3 eggs [in shells] and add equal weight of fat, flour and sugar.]
What is a ratio of two numbers that have different units?
If the measurements are of like things (eg distances) to find the ratio convert one of them into the units of the other, then the units an be dropped and the ratio simplified; eg: What is the ratio of 2 cm = 1 km? 1 m = 100 cm 1 km = 1000 m = 1000 × 100 cm = 100,000 cm → 2 cm : 1 km = 2 cm : 100,000 cm = 2 : 100,000 = 1 : 50,000 (This is the scale of the OS Landranger maps). If they are different things, then the units cannot be dropped, and the ratio requires them, eg making a brine solution may require 1 g of salt per 100 ml of distilled water the ratio of salt : water = 1 g : 100 ml.
What is considered a standard size map scale?
There is no standard. However, having said that, if you buy a map book or sheet, there are various scales which are generally used: 1:221,760 (1 inch = 3½ miles) 1:63,360 (1 inch = 1 mile - no longer issued by OS) 1:50,000 (2 cm = 1 km - the OS Landranger series, replacing the 1:63,360 series) 1:25,000 (4 cm = 1 km - the OS Pathfinder series) The scale chosen depends upon the use. The smaller the scale (the second number above) the more detail that can be put on the map. The first example scale above is a map book for driving and generally shows major roads and some minor roads to allow for route planning. The second/third examples can be used for driving, cycling or walking as they show roads, bridal ways, footpaths The last example is good for walking as it shows more detail including field boundaries. Maps with even smaller second numbers are used by specialist surveyors, eg to show property boundaries. Atlases have a much larger second number. The larger the second number, the less details that can be put (accurately) on the map.
What do dashes usually mean on a map?
Its meaning depends upon its colour, length and map it is on.On the Ordinance Survey Landranger series of map (1:50,000) a dash can represent:Long thick blue: Motorway under constructionLong thick red: A-Road under constructionBlack fairly short down the edge of a road symbol: an unfenced section of roadBlack fairly short: a path (not necessarily a right of way)Red fairly short: a bridlewayLong thin black: railway under constructionPair of short black: railway in a tunnel (if continuation of railway track)Black fairly short with arrow heads: pipeline (arrows show direction of flow)Black, fairly log (alongside water): towpathPair of short black across water: ford (if continuation of road)Pair of light blue: canal (dry)On the Ordinance Survey Explorer series of maps (1:25,000) a dash can represent some of the above as well as:Green fairly long: BridlewayLight orange short: permissive footpathLight orange long: permissive bridlewayBlack short: Electricity transmission line (other symbols along it represent pylons and poles)Black short: Edge of a Gravel/Sand/Other Pit or Quarry
In archaeology does the scale 1 is to twenty mean 1 cm on paper is twenty cm OR 1 cm on paper is 2 cm?
A scale of map:real or 1:20 means that for every 1 whatever unit on the map [paper], there are 20 of the same units in the real [world]. So 1 cm on the paper would be 20 cm in the real world. 1 mm on the paper would be 20 mm in the real world; 1 m on the paper would be 20 mm in the real world, etc. A map with a scale of 1:50,000, for example, means that every 1 cm on the map equals 50,000 cm in the real world: 1 : 50,000 → 1 cm : 50,000 cm However, scales are ratios and can be treated like a fraction with the colon like the fraction bar - you can multiply or divide both sides by the same factor and it remains the same; so multiplying above by 2 gives: 1 cm : 50,000 cm → 2 cm = 100,000 cm When there are units, they can be converted to other units: 100 cm = 1 m 1000 m = 1 km 2 cm = 100,000 cm → 2 cm = 1,000 m → 2 cm = 1 Km So for a 1:50,000 map, 2 cm on the map equals 1 km in the real world; this is the scale used in the Landranger series of maps, the replacement for the old 1 inch equals 1 mile (or scale 1:63,360) maps.
