Homework Help: physics

Posted by meredith on Friday, June 1, 2007 at 7:31pm.

A uniform plank of length 5.6 m and weight 203 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 440 N walk on the overhanging part of the plank before it just begins to tip

Write the sum of moments equation about any point, set it to zero. Remember the sum of vertical forces is zero.

I will be happy to critique your thinking or work.
