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 ...
I'm realizing I'd first try to solve it for the case with no friction. I think it'd look like this: If there's no friction then the tension in the wire will be uniform and equal to the external force applied on it so F=T1=T2. From the geometry of the problem it is possible...
The magnitude of the frictional force is often directly proportional to the normal force, or the force pressing the two surfaces against each other. The constant of proportionality varies depending on the surfaces which are in contact. For example, you might expect smaller friction when two "slick...

One approach to solve this is to use constraint equations that ensure that vectors are perpendicular instead. To this end, we define two additional vectors on the ith segment, denoted ti and ni, that are perpendicular to each other and to si, i.e., by making sure that they together form...
In this equation, the added mass and drag coefficients cA and cD, respectively, need to be determined through empirical relations. Besides that, the Morison equation can be applied in a straight-forward manner and allows to solve for wave forces in the time domain, which makes it a popular ...
Therefore the magnetic field observed on the solar surface can be incorporated into the formulation directly and a standard numerical technique, the boundary element method, can be applied to solve the field. A numerical test case demonstrates the power of the method by recovering the analytical ...
It is usually a good idea to set the guess values and (possibly) the lower and upper bounds for the variables before attempting to solve the equations. This is done with the Variable Information command in theOptionsmenu. Before displaying the Variable Information dialog, EES checks syntax and...

However such a simple elimination leads to p=Df, which, although usable in singlemode problems, is clearly inadequate in multimode scenarios because it overlooks pulse broadening. Instead we solve formally Eq. (24b) as ref. 48,49,50,51,52 p=(1+ΩG−1∂t)−1Df. (8) In Fourier...
