Pendulums in a sentence

Gridiron pendulums adjust to temperature changes faster than mercury pendulums, but scientists found that friction of the rods sliding in their holes in the frame caused gridiron pendulums to adjust in a series of tiny jumps.

Coupled pendulums Two pendulums with the same period coupled by suspending them from a common support string.

Gridiron pendulums became so associated with good quality that, to this day, many ordinary clock pendulums have decorative 'fake' gridirons that don't actually have any temperature compensation function.

The difference between clock pendulums and gravimeter pendulums is that to measure gravity, the pendulum's length as well as its period has to be measured.

However, as these sort of pendulums swing from one side to the other, as you will know, I think it’s swung very, very far in the direction of unfairness and not allowing people– and I’m not just talking about myself, but a whole lot of people.

It’s like finding two different pendulums that are weakly coupled to swing in opposite directions moving together in time.

Munich-born Heike Brachlow, now working not far from London, carefully balances her highly varied, colorful, and ingenious glass objects—expect precarious pendulums, columns, tops, and wobbly cylinders.

Balance wheels and pendulums always include a means of adjusting the rate of the timepiece.

Coupled oscillations Two pendulums with the same period fixed on a string act as pair of coupled oscillators.

During the 18th and 19th century, the pendulum clock 's role as the most accurate timekeeper motivated much practical research into improving pendulums.

Escapement Pendulums (unlike, for example, quartz crystals) have a low enough Q that the disturbance caused by the impulses to keep them moving is generally the limiting factor on their timekeeping accuracy.

For these reasons mercury pendulums were used in the highest precision clocks, but gridirons were used in quality regulator clocks.

He first employed freeswinging pendulums in simple timing applications.

Huygens was inspired by investigations of pendulums by Galileo Galilei beginning around 1602.

In walking, the legs act as pendulums, with the hips and shoulders rising and falling while the foot is planted on the ground.

It has traditionally been used to make knife-edge bearings for laboratory balances and precision pendulums, and sometimes to make mortars and pestles to crush and mix chemicals.

Measuring gravity with an invariable pendulum, Madras, India, 1821 * Invariable pendulums: Kater introduced the idea of relative gravity measurements, to supplement the absolute measurements made by a Kater's pendulum.

Mercury pendulums were the standard used in precision regulator clocks into the 20th century.

Precision pendulums are suspended on low friction pivots consisting of triangular shaped 'knife' edges resting on agate plates.

Randel, D., ed., The New Harvard Dictionary of Music, Harvard University Press, 1986, Tempo Before the metronome, it was difficult to specify the tempo of a composition; attempts were made using pendulums or the human pulse.
