Answers To Last Weeks Questions.

! Improper engagement of tht
| planetary systems low or reverse
speeds would be caused by slipping
brake bands, Tightening of the
brake band around its drum is the
remedy, unless Innings of the
brakes are badly worn, when they
must be replaced to give efficient
service.
2--Too rich a fuel mixture will
cause the motor to become hot and
sluggish in it's operation, and will
require the cooling system to do
more than its required amount OF
work in absorbing the excessive
heat. I.a.s
3-Changes in a rear axle gear
ratio do not alter the horse power
of a motor, but do change the
motors speed, also the driving
torque of the rear wheels.
4-Circulation of water in
thermo- syphon cooling system is
maintained by the law that water
when heated will rise and be re-
placed by water of lower temper
allure. In this system cool water
passed. through the water jacket
inlet from the bottom of the radi-
ator, rises to the top of the motors
water jacket when heated, and en-
tiers the top of the radiator through
the water jacket outlet Circula-
ton is automatic while the motor
is running if the proper water level
is maintained in the radiator.
5-A cause of abnormal dis
charge" reading at the ammeter nf
an electric system is excessive use of
current either for lamps of too
high amperage, q larger number of
lamps in use than is required or
by a ground contact of lamp wire
with some metal part of the car.
"a double ignition system is a
system having two separate means
of ignition, magnetic or battery
and coil, with one set of spark
plugs: ..a
Angular load exerted on a
bearing means that the load the
bearing, carries is exerted at an
angle, between horizontal and YER
teal, to the shaft on which it is
mounted.
S@SCauses of the car pulling hard
or running slowly although the
engine is albright are dry or worn
clutch leather, causing binding
when released or slipping when en-
gagged weak clutch spring which
will cause slipping or brakes adj
justed too tightly or not entirely
released. - b
9---Six causes for explosion in
the inlet pipe or in the carburetor
are: leaking valves, valves out of
time, weak inlet valve spring, in
let valve warped, pitted or it's
closing shindered by particles of
carbon, or sticking valve STEM,
over retarded spark especially
when the throttle is opened and
poor fuel mixture. Ns-
= 10--Piston speed is determined
by multiplying the length OF stroke
of the piston in inches by two,
multiplying the result by the num-
Der of revolutions per minute of
the crankshaft and then dividing
the product by twelve. The result
will be piston speed in feet per
minute.
