Physics Help please!!!

1) A uniform horizontal gantry 3.7 meters long which weighs 1000 N is supported at each end by a pillar. A railway signal weighing 111 N is suspended at 1.05 m from the end of the gantry.

Calculate the load (in N) on the pillar furthest from the signal.

2) A uniform horizontal gantry 3.7 meters long which weighs 1000 N is supported at each end by a pillar. A railway signal weighing 111 N is suspended at 1.05 m from the end of the gantry.

Calculate the load (in N) on the pillar closest to the signal.

How would I go about answering these?

Draw a diagram, then decide on a pillar to take moments about. One of the pillars will get you Q1, the other Q2.

Once you get the force on one pillar, you can resolve vertical forces if you don't want to do moments again.
