The most sufisticated collection of slide rule apps for iOS !
The slide rule (also known as slipstick) is an mechanical analog computer which can perform various scientific calculations. It consist of three linear strips and a sliding cursor and is used for multiplication, division, square, cube, square root, cubic root, trigonometry, logarithm and so on. Slide rules were used for many of years and in some regards can be much more useful than digital calculators.
The CubeSlideRule Lite is an implementation of a slide rule with the most popular logarithmic scales: A [B,Cl,C] D.
The high quality graphics makes it indistinguishable with a real mechanical slide rule, especially on devices equipped with Retina Display.
It can be used as a mechanical slide rule replacement in real engineering calculations. Also can be used as an educational tool for courser in mathematics. Simple how to use instructions are conveniently attached on the back side.
The CubeSlideRule is an implementation of a 10 inch Duplex Log-Log Slide Rule with scales:
T1, T2, K1, A [B, B1, K2, CF, CI, C] D, P, S, ST LL00, LL01, LL02, A [B, LL03, L, LL, LL3, C] D, LL2, LL1, LL0
These special combinations of scales are developed according to the best practices of the famous slide rule manufactures.
The psychrometric slide rule can be used to calculate with analog-like accuracy dew point temperature, relative humidity, humidity ratio, vapor pressure and enthalpy from wet bulb and dry bulb temperature readings in range from -5ºC to 55ºC (23ºF to 131 ºF ) at 750 Torr (mmHg) air pressure.
Easy to follow examples and simple descriptions of the used scales are placed on the back of the slide rule. Also conversion tables of related physical units of measurement are included.
The slide rule can be practically useful for professionals dealing with psychrometric calculations in various domains as agronomy, physics, air conditioners installment, etc. Also the slide rule can be used as an education tool.
