UNIT FIVE: TEXT QUESTIONS
Review Questions
1. What is the difference between an internal
combustion engine and an external combustion
engine?
The external combustion engine ignites its fuel outside of the
engine, while the internal combustion engine ignites its fuel inside
the engine.
2. How is the field of physics related to mechanical
engineering?
On the way engineering observes objects at rest and the dynamics
of objects in motion, both inherent concerns of mechanics.
3. Explain the law of conservation of energy and
why it is important for mechanics.
It states that energy is continuous; it cannot be created or
destroyed, only altered from one form to another. It’s important
because it lets us create very precise laws which connect to
each other.
4. What is the goal of improving combustion
modes?
Converting thermal energy and increasing the efficiency of the
vehicle.
5. What are the advantages of a higher degree in
engineering?
Most relative positions pay a median wage of about $83,000 a year
