When a weight is reciprocated, the equal and opposite force required for its acceleration at any instant appears as an unbalanced force on the frame of the machine to which the weight belongs.
The unbalanced masses of a locomotive may be divided into two parts, namely, masses which revolve, as the crank-pins, the crank-cheeks, the couplingrods, &c.; and masses which reciprocate, made up of the piston, piston-rod, cross-head and a certain proportion of the connecting-rod.
" It has hitherto been considered necessary owing to financial embarrassment, to commence financial years with unbalanced budgets.
His discontent found vent in the passionate, unbalanced lyrics of this period.
Deflecting Force for Translation in a Curved Path.In machinery, deflecting force is supplied by the tenacity of some piece, such as a crank, which guides the deflected body in its curved path, and is unbalanced, being employed in producing deflexion, and not in balancing another force.
The point was made keener by the fact that Knox's own Confession of Faith (like all those of that age, in which an unbalanced monarchical power culminated) had held kings to be appointed "for maintenance of the true religion," and suppression of the false; and the reformer now fell back on 1 John Hill Burton (Hist.
If the centre of gravity of a pulley is on the axis of rotation, and the whole mass is distributed so that the axis of inertia coincides with the axis of rotation, there can be no unbalanced force or unbalanced couple as the pulley revolves.
Is the unbalanced effort required.
Let M be the moment of the unbalanced couple required to produce the deviation; ther by equation 57, 104, the energy exerted by this couple in tht interval dt is Macit, which, being equated to the variation of energy gives da R2W da -
Since in his mission to Normandy he had been very moderate, it is possible that, as he was nervous and ill when sent to Nantes, his mind had become unbalanced by the atrocities committed by the Vendean and royalist armies.
Again, rapidly changing forces, due to the moving parts of the engine which are unbalanced vertically, act on the bridge; and, lastly, inequalities of level at the rail ends give rise to shocks.
The magnitude of the unbalanced force, for a mass of w pounds at a radius of r feet and a velocity of v feet per second, is expressed by wv 2 /gr lb; and, since the force varies as the square of the velocity, it is necessary carefully to balance a pulley running at a high speed to prevent injurious vibrations.
The boy varied the monotony of his studies by pranks which revealed his unbalanced character, including an attempt to raise spirits with the aid of Dr Faust's Hallenzwang.
The component across the direction of motion is a lateral pressure; the unbalanced lateral pressure on any piece, or part of a piece, is deflecting force.
When the four cranks are placed with two pairs at 180°, the pairs being at 90°, the forces are balanced without the introduction of a hammer-blow, but there remain large unbalanced couples, which if balanced by means of revolving weights in the wheels again reintroduce the hammerblow, and if left unbalanced tend to make the engine oscillate in a horizontal plane at high speed.
Unbalanced torque acting on the beam is 4r11) - p} lb ft.
His chief defect was an over-sensitiveness, leading to peevish and unreasonable behaviour in his private and official relations, to hasty and unbalanced judgments of persons and things that had given him annoyance, and to a despondency and discouragement which frustrated the great good he might have effected as a philosophic critic of public affairs.
A director, whose aim is only the personal advantage of the one who is receiving the exercises, will be the faithful interpreter of his founder's intentions: but in the case of one whose esprit de corps is unbalanced, the temporary and pecuniary advantage of the Society may be made of more importance than that of the exercitant.
There may be or may not be an unbalanced component in this pressure, due to the deviated motion.
