    Solution for mixed differential and algebraic equations

    Nobody? I guess this is a DAE problem (Differential Algebraic Equation) and will not be easy to solve with numerical integration. Maybe it will be easier to just modify the problem in a way I end up with just a set of ordinary differential equations. But this requires to seprate the lower...

    Solution for mixed differential and algebraic equations

    I'm confused finding a solution (numerical integration is ok) for the following model: http://imageshack.com/a/img27/7080/brmb.jpg Free body diagrams: http://imageshack.com/a/img22/9523/r0is.jpg And the equations of motion: \begin{align} k_{s,1}x_1+k_{s,2}x_1^3+k_m(x_1-x_2)+k_f(x_1-x_3) &=...

    Calculate point on line, perpendicular and intersecting another line in 3d space

    Hello All, I am looking for a way to find a point on a line (eg. line 1). This line has a perpendicular which has an intersection with another line in 3d space (line 2). I have the coordinates of line 1 and 2 and their direction vectors (lines have an infinite length). I also have the...
