How to apply force fonction of the time F(t)

Hello all!

I'am looking for define a force function of the time ; F(t).

I have a system, let's says a triangle, with 3 forces ( Fa,Fb,Fc) it is in equilibrium.

I would like Fb have a Dirac delta modulation.
(http://en.wikipedia.org/wiki/Dirac_delta_function)
Like a shock in fact!
I know that is really hard to make a model of a Diract delta force.
But at least it is possible to have Fb=2*Fb for 1 seconde? or x seconde.

My goal is to study the behaviour of a beam system under a perturbation.
After the perturbation (disturbance) I want to record the rotation and the translation of the system gravity center.

If you thinks you can help me ! welcome! :-)
thanks a lot !

Fred

Try the attached definition.

I've used the Kangaroo counter component, and a conditional so that the strength of the attraction force is normally zero but becomes high for an instant whenever the counter reaches a multiple of 50.

Hi Daniel !
Thanks for your so quick answer !
I tryed with conditional component, but i didn't mange to sort out my problem.

With you file , I get it ! thanks! :-)

Always easier with the solution!
Moreover I notice that timer is not necessary liked to Kangaroo component, can be upstream.

thanks,
