/ 162.2 = 168.914 919 9
(a)
The
Moon acceleration on Earth decreases in the same proportion:
0.003
439 282 / 168.914 919 9 = 0.000 020 361 cm/s2.
(b)
Without
the Eclipse, the decreasing acceleration on Earth is the sum of the
Sun (3) and Moon's (2) acceleration:
0.593069844
+ 0.003439282 = 0.596509126 cm/s2.
(c)
During
the Total Eclipse (Maximum effect):
0.593
069 844 + 0.000 020 361 = 0.593 090 205 cm/s2.
(d)
The
expected decreasing acceleration is then:
0.596
509 126 ö 0.593 090 205 = 0.003 418 921 cm/s2.
(e)
= 3.418 10-3 cm/s2
This
means that during the Total Eclipse, the gravitational force on Earth
increases by 3.418 10-3 cm/s2 with respect to its value before
the eclipse. Foucault's pendulum period decreases and the Torsion pendulum
period increases.

Period
Calculation
The
Torsion Pendulum at Harvard is a Torus suspended by a thread (string).
We know that its weight is 23.4 Kg.
The Period (T) of a Torsion Pendulum is related to the Torus Inertial
Moment (I) and the thread constant torsion
by the following equation:
(1)
(2)
Where
M = Weight and R the Torus Radius.
Supposing
that R = 0.5 m (3)
I
= 2.925 (4)
Now
it is possible to calculate the Constant Torsion
(5)
As
point of reference we will take 29.572 s, that is the average Period
before the Eclipse in Fig. 3, when the Gravitational Acceleration is
the Newton Acceleration, that the pendulum needs to measure - to detect
- if we are expecting to measure a different value during the Eclipse.
(6)
The
Torus weight variation is given by a simple proportion
(980.596 509 126 * 23.4) / 979. 403 490 874 = 23. 428 503 71 Kg.
(7)
It
is now possible to calculate I using this weight.
(9)
This
value is pointed out in Fig. 3 by and arrow.
Repeating
the same steps, (7) to (9), the AD values is calculated
(980.021 746 179 * 23.4) / 979.403 490 874 = 23.414 771 41 Kg
(10)
(11)
(12)
It
is possible to see in Fig. 3 that this value corresponds to the 29.580
5 s measured at Harvard..
AD
explains perfectly the phenomenon conceptually, that is QUALITATIVELY.
The AD value of 3.418 10-3 is the smaller value expected
by AD during the eclipse. For AD the phenomenon only happens when the
Moon enters in the penumbra and especially in the umbra (Maximum value).
This apparently is confirmed because the Sun and Moon are nearly aligned
about once a month near the time of the new Moon and nothing was detected.
The AD calculation is made without knowing the Pico-Graviton absorption
by matter nor its cross section. It is true that B is smaller than A,
but the total quantity in the Sun cone that is going through the Moon
during the Eclipse is huge and this could change (currently unknown
to us) the absorption coefficient by matter and/or its cross section.
This could increase the AD value to match the value measured at Harvard.

Fig. 1.
Times required to traverse the fixed part of the path of oscillation
(ordinates) vs the hour at which the observations were made, from about
10 a. m. until nearly 4 p. m. (abscissas). The full line shows the observations
made on 7 March 1970, the day of the total eclipse. The short vertical
dashed lines, a, b, and c, show the times of onset, midpoint, and endpoint
of the eclipse. The curved dashed line shows the data taken two weeks
later, 21 March, when the sun and moon were on opposite sides of the
earth.
