Do I understand correctly that I need to find resultant moment which is measured in N*m units? 1. The railway crossing gate consists of the 110-kg gate arm having a center of mass at Ga and the 275-kg counterweight having a center of mass at Gw. Determine the magnitude and directional sense of the resultant moment produced by the weights about point B. 2. It's been only a week in university and I'm already struggling with Statics. I'm kind of lost which formula should I use to find required values? 3. I think that it is something like this: M=-1079.1 (Ga force vector going downwards in y-axis negative direction) * 2.5 - 2697.75 (Gw force vector going downwards in y-axis negative direction) * 0.5 = -4046.63 How wrong am I?
