A uniform plank of length 5.2 m and weight 213 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 445 N walk on the overhanging part of the plank before it just begins to tip?
I know you have to set the torque of the plank equal to the torque of the man and solve for his lever length. I just don't know how to get the torque of the plank.
