Several of the Guardians were in the kitchen making sandwiches or rifling through the massive pantry.
She didn't feel him rifling through her thoughts, but she sensed it was what he did.
She smiled and started rifling through the rack of suits.
When she was cleaned up, she set about doing what she did every morning: rifling through the sparse pantry then searching the mansion for more information.
(9) c 2 Ci If the shot is moving as if fired from a gun of calibre d inches, in which the rifling makes one turn in a pitch of n calibres or nd inches, so that the angle S of the rifling is given by tan S = ird/nd = 2 d p/u, (10) '°If a denotes the density of the metal, and if the shell has a cavity homothetic with the external ellipsoidal shape, a fraction f of the linear scale; then the volume of a round shot being sird 3, and sird 3 x of a shot x calibres long W =*ird 3 x(I -f 3)v, (20) 2 Wki 2= 61rd 3 xo(I-f 5)Q, (21) Wk22=67rd3x 2 2+0 2(I - f5)Q.
Table of Rifling for Stability of an Elongated Projectile, x Calibres long, giving S the Angle of Rifling, and n the Pitch of Rifling in Calibres.
The introduction of rifling necessitated an improvement in sights and an important modification in them.
It is evidently a gyroscopic effect, being reversed in direction by a change from a right to a left-handed twist of rifling, and being increased by an increase of rotation of the shot.
After a certain discount for friction and the recoil of the gun, the net work realized by the powder-gas as the shot advances AM is represented by the area Acpm, and this is equated to the kinetic energy e of the shot, in foot-tons, (I) e d2 I + p, a in which the factor 4(k 2 /d 2)tan 2 S represents the fraction due to the rotation of the shot, of diameter d and axial radius of gyration k, and S represents the angle of the rifling; this factor may be ignored in the subsequent calculations as small, less than I %.
Its burrows are sought after in the countries where it abounds, both for capturing the animal and for rifling its store.
In Lower Egypt practically all the mummies have perished; but in Upper Egypt, as they were put out of reach of the inundation, the cemeteries, in spite of rifling and burning, yield immense numbers of preserved bodies and skeletons; attention has from time to time been directed to the scientific examination of these in order to ascertain race, cause of death, traces of accident or disease, and the surgical or medical processes which they had undergone during life, &c. This department of research has been greatly developed by Dr Elliott Smith in Cairo.
