    A uniform plank of length 5.0m rests horizontally on two bricks that are 0.5m from either end. A child of weight 200N stands on one end of the plank and causes the other end to lift, so it is no longer supported at that end.

    Calculate
    a - The weight of the plank
    b - the support force acting on the plank from the supporting brick

    The answers are 50N and 250N respectively, but I don't know how to get to them. Could someone give a step by step guide if possible?

    Thanks
