A uniform beam AB AB\,AB has length L L\,L m and mass M M\,M kg. Loads of weight 2W N and W W\,W N are attached at A A\,A and BBB, respectively. The beam is held horizontally by one vertical support at a point PPP, where AP=xAP = xAP=x m.
Show that x=L(Mg+2W)2(Mg+3W)x = \dfrac{L(Mg + 2W)}{2(Mg + 3W)}x=2(Mg+3W)L(Mg+2W).
