A uniform horizontal gantry 3.6 meters long which weighs 1000 N is supported at each end by a pillar. A railway signal weighing 300 N is suspended at 0.68 m from the end of the gantry.Calculate the load (in N) on the pillar furthest and closest from the signal.

You take moments. In this case I imagine you'll be taking moments around one of the pillars, and assuming the gantry has a uniform mass distribution. If you don't know what taking moments about a pivot necessitates, then go back and read your class material.
