    Hi sstangle

    Draw a free body diagram and find all the forces acting on the rod. Then set the net forces that are parallel to the rail equals to zero

    No, that's not the right equation. You have to find the forces parallel to the rail and they are not mg and BQV. Actually you need to use F = BIL sin θ
