Chapter 12.1, Problem 1cT
Imagine that a small hole is opened in the container wall near the bottom of each layer.
1. Predict what will happen to the water near each hole. Explain.
2. Check your prediction by observing the demonstration. Record your observations. (Asketch may be helpful.)
What do your observations suggest about: (1) the existence of horizontal forces on thethree layers of water in pan A? (2) the relative magnitudes of the horizontal forces onthe three layers?
If necessary, revise your free-body diagrams in part A so that they are consistent withyour answers.

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to
support any additional load. Consider a leaf spring constant of 5.45 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y = 0.500 m.
