The board sandwiched between two other boards weighs 95.5 N. If the coefficient of friction between the boards is .663, what must be the magnitude of the comrssion forces (assume horizontal acting on both sides of the center board to keep it from slipping?(adsbygoogle = window.adsbygoogle || []).push({});

I have no idea how to do this problem...is the normal force 95.5 (if so then i can solve for friction but i wouldnt know what to do then...The answer is 72 N..so if somebody can show me how to do this problem i would greatly appreciate is.....

thank you
