| Q.-ls 1t true that In q bearing thu
friction Is less If the bearing and axle
are of different metals, than II the,
are OF the same materials?
Ans.-E. S. Keene, dean department
Of engineering and physics.
Practice has shown that a journal
made o. the same metal as the journal
box does not wear we'll Under such
conditions the bearing soon wears out
1t 10 customary to make journal boxes
with lining Of softer. tougher metal
than that Of the journal Usually Bah.
bett metal 10 used for such purposes,
but brass and bronze are commonly
used. Bearings made In this way give
less friction and, ~ q consequence,
last longer
GLOW much nitrogen does alfalfa
put In the soil in year?
Ans.-E. F. Ladd, dean chemistry
department
1T 10 not possible to say the exact
amount Of nitrogen that would be add
ed to the soil through the growth Of
alfalfa for the period Of one year. II
Is generally stated, from experiments
that have been made, that the amount
OF organic matter included In the roots
and stubble is just about equal to the
amount removed in the crop Of alfalfa
or clover. and that the nitrogen con-
tent Is about the same for the two Dor.
tons
4 recent analysis of sample of al. i
falfa grown In this state showed the
nitrogen content to be 2s5 per cent. !
II a crop in season amounted to
hfee tons, 5000 pounds, and that por.
Ion, including stubble and roots be-
heath the surface, were equal to that
'emoved, then the amount OF nitrogen
'emaining in the roots and stubble
you'd be equal to about III pounds.
n other words, there has been gath !
:red from the atmosphere and from
he various strata Of the soi; =
pounds Of nitrogen per acre and
brought into the form Of organic nitro
zen that will become easily available
or plant growth but more than that.
he distribution of this product
the surface soil and the
arge amount Of organic matter. have
made other changes which are vastly
important,
Q.-What IL the difference between
magnetic and a dynamo?
Ans.-R. NJ. Dolve, professor agrt
ultural engineering
The essential difference ia that the
ynamo has electro field magnets,
Vhale the magnetic has permanent
eld magnets. That is, the dynamo
as sll Or part Of the current genera
ed BY Il pass through fts field wind
,gs for the purpose Of exciting the
cid magnets. which are made Of soft
ION. The field magnets Of the mag.
eto are made Of tempered steel and
re permanent magnets requiring no
findings
