You cross a horizontal rigid bridge of uniform density and length L. The bridge weighs 3671 and is resting on two concrete pillars, one at each end. You cross 1/5 of the length of the bridge and stop. If your weight is 1030.22 N, what is the magnitude (no sign) of the force that the first concrete pillar exerts on the bridge? That pillar is 1/5 of the length away from you, back where you started to cross.
