Given: m$=5$ ft$,$ n$=10$ ft$,$ the angle$$ of the incline is $29$ degrees, the force P is applied at height h $=7$ feet, and the weight of the box is $35$ lb

Find: the maximum force P that can be applied without tipping the box.

Assume that

$1)$ the friction coefficient is high enough to prevent slipping and

$2)$ the center of gravity of the box is at the box's geometric center.$$
