![]() ![]() For the first, it's to find the root of $f$, for the second, given a function $f$ we want to minimize, we need the root of $f'$. This is a Kinematic and Static Analysis of a four-bar linkage done with Matlab - Four-bar-Linkage-Analysis/newtonraphson. So it's the exact same thing! In both cases, we are using Newton's method. There are two methods of solutions for the load flow using the Newton Raphson Method. How do we find the point where the derivative is zero? We use the Newton's method from above! But now the function $f$ is $g'$ (since we want $g'$, and not $g$, to be zero!), so instead of $f$ and $f'$ used in Newton's method, we plug in $g'$ for $f$ and $g''$ for $f'$. Newton Raphson Method is an iterative technique for solving a set of various nonlinear equations with an equal number of unknowns. ![]() Newton's method is a method to find the root of a function $f$, i.e. The question that is being answered in both articles are slightly different, and you're (very understandably) getting confused by the consistent usage of a function $f$ in both articles when they are serving different purposes! deterministic methods where a number of coupler poses are prescribed to synthesize the four-bar mechanism using the. These equations are solved by the Newton-Raphson method, where the initial method coordinates are given by the genetic algorithm. ![]()
