I have a rectangular bar in between two rectangular bars ( a sandwich ). The outer two bars are attached to springs on the outer sides and press against the middle bar with a force of N ( due to springs ) thus acting as support for the middle bar. The middle bar has a free translation motion ( under the effect of friction due to contact in outer two bars). The question is that what should be the value of ' N ' if the middle bar is pulled with a force of 100 Lbs ( for example ) ? Please help out ...
