2. Fuller calculator - Wikipedia

   en.wikipedia.org/wiki/Fuller_calculator

   The calculator described above was called "Model No. 1" . [6] Model 2 had scales on the inner cylinder for calculating logs and sines.The "Fuller-Bakewell" model 3 had two scales of angles printed on the inner cylinder to calculate cosine² and sine ⋅ cosine [note 1] for use by engineers and surveyors for tacheometry calculations.

3. Engine displacement - Wikipedia

   en.wikipedia.org/wiki/Engine_displacement

   Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...

4. Compression ratio - Wikipedia

   en.wikipedia.org/wiki/Compression_ratio

   Absolute cylinder pressure is used to calculate the dynamic compression ratio, using the following formula: = where is a polytropic value for the ratio of specific heats for the combustion gases at the temperatures present (this compensates for the temperature rise caused by compression, as well as heat lost to the cylinder)

5. Cylinder - Wikipedia

   en.wikipedia.org/wiki/Cylinder

   The bare term cylinder often refers to a solid cylinder with circular ends perpendicular to the axis, that is, a right circular cylinder, as shown in the figure. The cylindrical surface without the ends is called an open cylinder. The formulae for the surface area and the volume of a right circular cylinder have been known from early antiquity.

6. Piston motion equations - Wikipedia

   To convert the angle domain equations to time domain, first replace A with ωt, and then scale for angular velocity as follows: multiply ′ by ω, and multiply ″ by ω². Velocity maxima and minima

7. Bushel - Wikipedia

   en.wikipedia.org/wiki/Bushel

   The Winchester bushel is the volume of a cylinder 18.5 in (470 mm) in diameter and 8 in (200 mm) high, which gives an irrational number of approximately 2150.4202 cubic inches. [4] The modern American or US bushel is a variant of this, rounded to exactly 2150.42 cubic inches, less than one part per ten million less. [ 5 ]
