Does anyone know how I can calculate the impact force/energy of a sphere falling onto a fluid?
I know the geometry and mass of the ball, the height it has fallen (so can calculate a velocity at impact), and i know the properties of the fluid its being dropped onto.
the real life situation is a...
Hi guys,

time_t t;
srand(unsigned (time(&t)));
int num = (rand() % 49);
but as that stands, the numbers im getting dont seem very random. in fact they seem like theyre just being plucked from a...

i need to explode a series of polylines into their constituent parts to re-position certain aspects of my drawing, and i know that when you do this, you lose the width, and the plines become lines. is there any way of reassigning a width to these lines to make them polylines again without...
