A uniform plank of length 5.8 m and weight 216 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 441 N walk on the overhanging part of the plank before it just begins to tip?
This is what I did:
I took the weight of the plank and multiplied by the hanging support. I next set that equal to the weight of the person times x distance
So it looks like:
216(1.1)=441x
I solved for x and got
x=0.539
but it's wrong...what do I do?
