As you stretch the frame then the cross beams have tension, heavy blow you force them into compression. Now do we look at the mechanical impedance or the mechanical reactance? Do we look up, or look down? mmmmmmmmm Integration or differential calculus. OMG lets not go there? Back under my rock and grin ric. Rubbing my bones in glee. Regards Roger
