Question

technician a says that engine displacement can be measured in cubic inches, cubic centimeters, or liters. technician b says that to find displacement you need to know the bore, the stroke, and the number of cylinders. who is correct?

a. technician a

b. technician b

c. both technician a and technician b

d. neither technician a nor technician b

Explanation:

• For Technician A: Engine displacement (volume of all cylinders) can indeed be measured in cubic inches, cubic centimeters, or liters (since these are volume units).
• For Technician B: The formula for engine displacement is \( \text{Displacement} = \pi \times (\frac{\text{bore}}{2})^2 \times \text{stroke} \times \text{number of cylinders} \), so knowing bore, stroke, and number of cylinders is necessary to calculate displacement. Thus, both are correct.

Answer:

c. Both Technician A and Technician B
