point in the cycle in every cylinder.
VIII you please define alternating and
direct current, cantiiever strings, open
circuit?
An alternating current is II which
at certain definite intervals changes
its direction and value.
A direct current is one which flows
in one direction only. Direct current
is that given by storage batteries, dry
cells. etc. a cantilever spring appears
like a semielliptic spring reversed.
mounted on a trunnion, and n end Is
fastened rigidly to the rear axle hous-
ing, while the other end is shackled.
An open circuit refers to an electric
ity carrying conductor which is broken
at some point. SO that it does not form
a complete path for the current. If Il
wire is broken the circuit is open. be
cause the current has no path. When
a lighting switch is thrown to off posi-
ton the circuit is opened, no current
can flow. and hence the lights go out.
Can you give the cause of a piston
sticking?
Lack of fabrication or operating the
motor without water is a common
cause.
What is the meaning of chrome-vana-
dunn, phosphor bronze, low carbon
steel?
Characterization steel is steel which
has been allowed with a certain per.
centage of vanadium. an element metal,
and also Il certain amount Of chromi
unl. another metal.
PhOsphor bronze is an alloy contain
ing copper. tin. lead and Il small per
centage Of phosphorus.
Low carbon steel Is that which has
Il small carbon content. usually be
tween 90 to 3 per cent.
In timing valves is it not a fact that
when the valves for piston No. I are
timed right all the valves will be timed
right where only one cam shaft is used,
as in Ar L head motor?
Yes, provided the valve tappeis are
adjusted properly for all valves. The
cams automatically take the proper pc
sition if the cams Of the first cylindcr
nre correctly placed.
What would be the best way to
Iopofbap $do drive cb at tram xha mar
box in increasing the wheel base Of a
car by three feet?
If you intend to carry the rear axle
back a distance of three feet the best
method of lengthening the drive shaft
would be TO cut ii somewhere in its
length and drive a piece Of seamless
steel tubing over each end of the shaft
a distance Of six inches Or more. The
tubing "A then be braZed or welded
to the shaft and a good connection
made between the two. 1t must be
remembered that in l%engthening the
wheel base Of a car it throws the entire
steering layout out of arrangement.
and as a result of this you will find a
tendency Of the car to skid. The cen
ter lines Of the hubs of the two front
wheels must intersect the line Of the
rear axle produced at a cOmmo point.
and his will not occur II you carry the
rear axle back from it's first position.
Can you tell mo how to increase the
life Of lamp bulbs?
Owing to the heat and vibration to
which the incandescent lamps in the
headlights are exposed the delicate fl
aments sometimes have a tendency to
droop downward. II this Is not cor
rected In time the 6lament will he
short circuited and the lamp ruined.
The dropping may be remedied by CIV
ing the lamp One-half turn. In this
manner gravity will slowly bend the
flaments back to the correct horizon
tai position.
