gomunkul51, I'll start from the beginning:
u is defined as displacement
u' is defined as velocity
u'' is defined as acceleration
I have an object that is excited by a time varying force. In this particular case, the force, F(t), is a linearly decreasing force with initial magnitude Fo...
Ok, so I've been working on this problem such that I can solve it with a numerical method. I am stuck because I am trying to isolate a variable, v, but I am left with a quadratic equation with two roots. Here's what I have:
u'' + A*(u')^2 = B*(1-t/td)
Introduce v=u', v'=u''...
Homework Statement
I'm trying to crudely approximately the distance individual masonry units fly when a blast load impacts a masonry wall. I'm a structures guy so I can calculate when the wall will failure, but I am having trouble with the calculus associated with the equation of motion.
My...
