An online calculator is available on www.tribonet.org that allows calculating Stribeck curve for line [16] and point [17] contacts. These tools are based on the load-sharing concept. Also molecular simulation based on classical force fields can be used for predicting the Stribeck curve. [18] Thereby, underlying molecular mechanisms can be ...

For example, at the coarsest level, a beam is just a 1D curve whose torque is a function of local curvature. At a more refined level, the beam is a 2D body whose stress-tensor is a function of local strain-tensor, and strain-tensor is a function of its deformation. The equations are then a PDE system.
The normal force N is equal, opposite, and collinear to the gravitational force mg so the net force and moment is zero. Consequently, the object is in a state of static mechanical equilibrium. In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero.
Hydrostatics, also known as fluid statics, is the study of fluids at rest (i.e. in static equilibrium). The characteristic of any fluid at rest is that the force exerted on any particle of the fluid is the same at all points at the same depth (or altitude) within the fluid.
Since there are four unknown forces (or variables) (V A, V B, V C, and H A) but only three equilibrium equations, this system of simultaneous equations does not have a unique solution. The structure is therefore classified as statically indeterminate.
The equivalence class of this relation simply a C r-curve. An even finer equivalence relation of oriented parametric C r-curves can be defined by requiring φ to satisfy φ ′ (t) > 0. Equivalent parametric C r-curves have the same image, and equivalent oriented parametric C r-curves even traverse the image in the same direction.
Let X be a vector field on M of class C r−1 and let p ∈ M. An integral curve for X passing through p at time t 0 is a curve α : J → M of class C r−1, defined on an open interval J of the real line R containing t 0, such that =;
