The reciprocating motion of a non-offset piston connected to a rotating crank through a connecting rod (as would be found in internal combustion engines) can be expressed by equations of motion. This article shows how these equations of motion can be derived using calculus as functions of angle ( angle domain ) and of time ( time domain ) .
The non-sinusoidal motion of the piston can be described in mathematical equations. Balance shaft system: 1922 design by the Lanchester Motor Company In a car, for example, such an engine with cylinders larger than about 500 cc/30 cuin [ citation needed ] (depending on a variety of factors) requires balance shafts to eliminate undesirable ...
Rotordynamics (or rotor dynamics) is a specialized branch of applied mechanics concerned with the behavior and diagnosis of rotating structures. It is commonly used to analyze the behavior of structures ranging from jet engines and steam turbines to auto engines and computer disk storage.
The mean piston speed is the average speed of the piston in a reciprocating engine. It is a function of stroke and RPM. There is a factor of 2 in the equation to account for one stroke to occur in 1/2 of a crank revolution (or alternatively: two strokes per one crank revolution) and a '60' to convert seconds from minutes in the RPM term.
These equations express the link lengths, L 1, L 2, and L 3, as a function of the stroke,(ΔR 4) max, the imbalance angle, β, and the angle of an arbitrary line M, θ M. Arbitrary line M is a designer-unique line that runs through the crank pivot point and the extreme retracted slider position. The 3 equations are as follows:

In classical mechanics, Euler's rotation equations are a vectorial quasilinear first-order ordinary differential equation describing the rotation of a rigid body, using a rotating reference frame with angular velocity ω whose axes are fixed to the body. They are named in honour of Leonhard Euler. Their general vector form is
