Here, were the Leith, Aberdeen, and Glasgow steamers, loading and unloading goods, and looking immensely high out of the water as we passed alongside; here, were colliers by the score and score, with the coal-whippers plunging off stages on deck, as counterweights
to measures of coal swinging up, which were then rattled over the side into barges; here, at her moorings was to-morrow's steamer for Rotterdam, of which we took good notice; and here to-morrow's for Hamburg, under whose bowsprit we crossed.
without examination, to deny what has been said, I wish it to be considered that the motion which I have now explained follows as necessarily from the very arrangement of the parts, which may be observed in the heart by the eye alone, and from the heat which may be felt with the fingers, and from the nature of the blood as learned from experience, as does the motion of a clock from the power, the situation, and shape of its counterweights
There has been a violent stress in one direction, and it needs a counterweight
Primary balancing of three-cylinder engines is done by counterweights
. In order to eliminate remaining vibrations, the methods of balance shaft and mass unbalancing of flywheel and crankshaft pulley have been used for reducing pitch moment as well as optimized mounts for reducing yaw moment.
Hence, we also study the strength of anti-corruption counterweights
, such as a free press, a system of checks and balances, auditors, accountability organizations or budgetary and spending regulations.
This paper adopted the hammering method to excite concrete beams with different pre-stress values, eccentricities and counterweights
based on two kinds of methods including experiment and numerical simulation, processed and analyzed the collected mid-span acceleration of beams to quantitatively analyze the relationship between the fundamental frequency of beams and pre-stress.
Additional accessories, including the polar alignment scope, counterweights
, and dovetail saddle, are purchased a la carte.
JCB has unveiled three new mini excavators at its headquarters in Staffordshire, UK, with operating weights of 1.6t to 1.8t, and feature steel bodywork designed to better protect hydraulic rams and hoses and swing-out counterweights
for ease of maintenance.
The new model also shares the same counterweight
system as the TMS9000E, so owners can interchange counterweights
and wing weights from the previous-generation crane, giving them flexibility in configurations across an entire fleet.
Clark also perfected the elaborate system of counterweights
used in all new theaters, which have scene-shifting problems.
