  A. suspend and resume

  B. enable and disable

  C. suspend, resume, enable and disable

• Question 6:

  Choose the correct answer.

  A system engineer has created the following model of a tank system composed of two tanks and a pipe connecting them:

  

  The system engineer wants to mathematically relate the flow of water through the pipe using the following mass conservation equation: Tank_System wFlowin flowRate * Tank_System pipe endA_Area = Tank_System wFlowOut flowRate * Tank_System pipe endB_Area How would the system engineer model this in SysML?

  A. Create a block to represent the mass conservation equation, use it in Tank_System. and relate its properties to the properties of wFlowin. wFlowOut. and pipe

  B. Create a constraint block to represent the mass conservation equation, use it in Tank_System. and relate its parameters to the properties of wFiowin. wFlowOut. and pipe

  C. Create a constraint block to represent each of wFlowin wFlowOut and the mass conservation equation; use these constraint blocks In Tank_System. and relate their parameters to the properties of pipe.

  D. Create two flow properties for Tank_System (equivalent to wFlowin and wFlowOut); create a constraint block for the mass conservation equation and use it in Tank_System.and then relate the flow properties to the new constraint property.

  E. It is not possible to model this because wFlowin and wFlowOut are item properties and not flow properties

  Correct Answer: C

• Question 7:

  Choose the correct answer What is a 'control operator'?

  A. it is an activity that can output control tokens via a parameter node.

  B. It Is the general term for any element of an activity that can handle control tokens.

  C. It Is a special kind of activity node that can be used to control the flow of tokens into an activity.

  D. It Is an activity node that allows a modeler to specify the use of mathematical operators such as plus minus, multiply, or divide.

  Correct Answer: B

• Question 8:
