Bob made paint, Beverly made nails.
The avifauna is varied and abundant, comprising eagles, vultures (protected by law), hawks, owls, pelicans, cranes, turkeys, geese, partridges " (called quail or " Bob White " elsewhere), ducks, &c., besides numerous smaller species, many of which are brilliant of plumage but harsh of voice.
I.): " Raise the sight, and if it keeps in line with a plumb bob, it can be as confidently relied upon as the line of metal, if the trunnions are horizontal.
It was ranged by varying the charge, and layed for line by means of a line and plumb bob Laying aligned on a picket.
Gamble's quail, bob-white, grouse, English pheasants and wild turkeys are the most important game birds, and the mocking-bird is common throughout south-western New Mexico.
The game birds include quail ("Bob White") and partridges.
Among game-birds there are a few wild turkeys, wild geese and bob-white (locally " partridge "), and greater numbers of grouse and various ducks; among song-birds the robin, bluebird and mocking-bird are common; and there are also woodpeckers, whippoorwills, blackbirds, hawks, owls, crows and buzzards.
" Achilles " of 9000 tons displacement it was found that moving 20 tons across the deck, a distance of 42 ft., caused the bob of a pendulum 20 ft.
This is called " quadrant elevation," and the proper inclination was given by means of the " gunner's quadrant," a quadrant and plumb bob, one leg being made long to rest in the bore, or by bringing lines scribed on the breech of the gun in line with a pointer on the carriage; these were called " quarter sights."
If the bob of the pendulum is iron, and if a coil is placed just below the centre of swing, then, if a current passes through the coil, while and only while the bob is moving towards it, the vibration is maintained.
By the use of a permanent magnet instead of a shunt coil as the bob of one pendulum, the meter can be made up as an ampere-hour meter.
Many species of ducks are also still found; and the reed-bird (bobolink), " partridge " (elsewhere called quail or " Bob White "), ruffed grouse (elsewhere called partridge), woodcock, snipe, plover and Carolina rail still abound.
For small earthquakes, in which the movement is rapid, the bob of a very long and heavy pendulum will practically comply with these conditions.
In the new position b would tend to follow the direction of its point of support, whilst c would tend to fall in the opposite direction, and the bob of one pendulum would exercise a restraint upon the motion of the other.
13, the horizontal motion of the bob is affected only by the horizontal component of the force acting upon it.
Hence if 1 be the length of the string, and x the horizontal displacement of the bob from the equilibrium position, the horizontal component of gravity is mgx/l, whence The motion is therefore simple-harmonic, of period r= 27ri/(l/g).
If the point of suspension have an imposed simple vibration f = a cos at in a horizontal line, the equation of small motion of the bob is mx= mg-l-,
For it can only depend on the mass m of the bob, the length 1 of the string, and the value of g at the place in question; and the above expression is the only combination of these symbols whose dimensions are those of a time, simply.
The motion of the bob of a spherical pendulum, i e.
If we produce OG to P, making OP =1, the point P is called the centre of oscillation; the bob of a simple pendulum of length OP suspended from 0 will keep step with the motion of P, if properly started.
In the normal mode corresponding to the former root, M swings almost like the bob of a simple pendulum of length a, being comparatively uninfluenced by the presence of m, whilst m executes a forced vibration (~I2) of the corresponding period.
In the second mode, M is nearly at rest las appears from the second of equations (ii)], whilst m swings almost like the bob of a simple pendulum of length b.
If, on the other hand M is small compared with in, u is nearly equal to unity, and the root1 of (12) are a2=g/(a+b) and fri_-=nigIM.(a~b)/ab, approximately The former root makes 0=4,, nearly; in the corresponding normal mode m oscillates like the bob of a simple pendulum of length a+b.
131 AO represents an upright axis or spindle; B a weightcalled a bob, suspended by rod OB from a horizontal axis at 0, carried by the vertical axis.
When the spindle 1 D is at rest the bob hangs close to it; when the spindle rotates, the bob, being made ~ c to revolve round it, diverges until the resultant of the centrifugal force and the weight of the bob is a force acting atO in the direction OB, and then it revolves steadily in a circle.
In finding the position in which the bob will revolve with a given angular velocity, a, for most practical cases connected with machinery the mass of the rod may be considered as insensible compared with that of the bob.
Let the bob be a sphere, and from the centre of that sphere draw BH=y perpendicular to OA.
Let OH=z; let W be the weight of the bob, F its centrifugal force.
132, not to a point in the vertical axis, but to the end of a projecting arm C, the position in which the bob will revolve will be the same as if the 0 rod were jointed to the point 0, where its prolongation cuts the vertical axis.
The latter, however, though thriving as an aviary bird, has failed at large in England, as did the bob-white (Onyx virginianus) both there and in New Zealand.
Among the game birds are quails ("Bob White"), "partridges" (ruffed grouse), ducks, geese, woodcocks, snipes and plovers.
The game birds include quail (Bob White), ruffed grouse and a few pinnated grouse (once very plentiful, then nearly exterminated, but now apparently reappearing under strict protection), and such water birds as the mallard duck, wood duck, blueand green-winged teals, Wilson's snipe, and greater and lesser yellow legs (snipe).
Among game birds are various species of ducks, the quail, or " Bob White," and the woodcock.
B is the bob of a pendulum, with its style s passing through a slot in the short arm of a light lever, sop, pivoted at o, and with its outer end resting upon a revolving cylinder covered with smoked paper.
Vicentini of Padua, will yield excellent diagrams of the gentle undulations of earthquakes which have originated at great distances, but for local disturbances, even if the bob of the pendulum acts as a steady point, the highly multiplied displacements are usually too great to be recorded.
If the current is on while the bob is receding the vibration is checked.
The Texas Bob White or Texas quail is found principally in Texas and a few neighbouring states.
It consists of a steelyard mounted on a fulcrum; one arm carries at its extremity a heavy bob and pointer, the latter moving along a scale affixed to the stand and serving to indicate when the beam is in its standard position.
Among the song-birds are the mocking-bird, the Carolina wren and the cardinal grosbeak (or red bird); there are plenty of quail or " bob white " (called partridge in the South).
Among the more common species of game are squirrels, opossums, musk-rats, rabbits, racoons, wild turkeys, ", partridges" (quail, or Bob White), geese, and ducks; deer, black bears, grey (or timber) wolves, black wolves and "wild cats" (lynx), once common, have become rare.
Somewhere in the distance a Bob-White quail called.
It looks easy enough, now that Bob has shown how it is done.
