Physics

A crowbar is used to wrench open a wooden crate. The crowbar is situated so that a point 8 cm from the end digging into the box acts as a pivot point. The crobar is gripped on the other side, 29 cm away from the pivot. If the person exerts a force of 110 lbs on the crobar, how much force is exerted by the crowbar on the box? [Answer in lbs]
