The force of the added water produces a torque on the dam. in a simple model, if the torque due to the water were enough to cause the dam to break free from its foundation, the dam would pivot about its base (point p). what is the magnitude τ of the torque about the point p due to the water in the reservoir?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
