Analysis
There are a variety of reinforcement conversations that
spring from this puzzle. The gasket leaks under high pressure, is evident from
the height of the second pulse pattern response curve. An important lesson is to make sure students
understand that the exponential rise and decay of the response pressure is an
expected behavior and not an indication of a gasket leak. These conversations can
include, when grade level appropriate, the exponential nature of this portion
of the response curve, the time constant concept and the analogous connection
that the exponential portion of the data has to the resistor in series with a
capacitor circuit response when an applied voltage (the RC series circuit
model) with the same step function pattern is applied. The math explanation of
this exponential response to students ranges from simple time constant
calculation, time constant connection to the 1/e response value, to the 1st
order differential equation for the RC series circuit model. Student Google
searches on these topics will provide a plethora of extra information.
The actuator should be shipped
to the customer. Answer: NO
