Is normal force always equal to weight? No. Normal force will generally be equal to weight for an object laying on horizontal surfaces. When the surface is inclined at an angle, the normal force will be equal to a component of the weight force. How do you calculate normal force? Normal ...
The same goes on with but that looks more like a "contact point" although it'll also deform creating a pressure area that has an equivalent force associated with it. What I think you need is to find out how the tension of the wire is related to the forces and . That's what I was...
force of kinetic friction by the normal force holding the two surfaces together. The equation that helps you to find the coefficient of kinetic friction is this:The normal force is the amount of force perpendicular to the surfaces that are in contact, or the force holding the objects toget...
To find the quantity of interest as a series expansion in a small parameter is the basic tenet of perturbation theory [3–7]. The obvious in the perturbation method flaw is that we frequently have no interest in the big parameter domain of the theory being investigated. Several solutions ...

According to the definition of [Math Processing Error]θk, it is easy to find that [Math Processing Error]θk′=0,when |x|<k or |x|>2k. Therefore, [Math Processing Error]−2k2∫0∞μ(s)∫Rnθk′u(x⋅∇ηt(s))dxds≤2γk2∫0∞μ(s)∫k≤|x|≤2k|u||x||∇ηt...
It did not cause anxiety that Maxwell’s equations did not apply to gravitation, since nobody expected to find any link between electricity and gravitation at that particular level. But now physics was faced with an entirely new situation. The same entity, light, was at once a wave and a ...

The explicit form of the orthogonal trajectories has been utilized to find implicit solutions of the vdP equation.关键词: Theoretical or Mathematical/ nonlinear differential equations relaxation oscillators Riccati equations/ ...
The objective is to find the conditions that will minimize Eq. (3.6) in order to obtain the optimal value Ji*,∀i so that (3.7)Ji*(εik,uik,u−ik)=minuikE∑K=0N−1Uiεik,uik,u−ik*, where the neighbors’ optimal strategies are denoted by u−ik* for each unit − ...
Our goal is to find an expression for the scalar field u(r) generated by the known source q(r). To do so, we select an arbitrary point r′ and around it draw a sphere, CR, with a radius great enough that the volume V falls within the ball OR bounded by the sphere CR; that ...
