Q. What effect would too much lead have.
A. It would also weaken the engine, as the steam would
enter before the piston had reached the end of the stroke, and
would tend to prevent it passing the center.
Q. What is the stroke of an engine?
A. It is the distance the piston travels in the cylinder.
Q. How do you find the speed of a piston per minute?
A. Double the stroke and multiply it by the number of
revolutions a minuet. Thus an engine with a 12 inch stroke
would travel 24 inches, or 2 feet, at a revolution. If it made
200 revolutions a minute, the travel of piston would be 400 feet
a minute.
Q. What is considered a horse power as applied to an
engine?
A. It is power sufficient to lift 33,000 pounds one foot high
in one minute.
Q. What is the indicated horse power of an engine?
A. It is the actual work done by the steam in the
cylinder as shown by an indicator.
Q. What is the actual horse power?
A. It is the power actually given off by the driving belt and
pulley.
Q. How would you find the horse power of an engine?
A.
