A uniform plank of length 400 m and weight 350 n rests, Ask an Expert

Academics

A uniform plank of length 4.00 m and weight 350 N rests horizontally on two supports, with 1.00 m of the plank hanging over the right support. A person who weighs 500 N walks on the overhanging part of the plank.

A) if the person is standing at x= 0.30 m to the right of point B, what is the value of the force FA?

B) What is the maximum value of the distance x before the plank begins to tip? Show work.
