A spring scale, spring balance or newton meter is a type of mechanical force gauge or weighing scale. It consists of a spring fixed at one end with a hook to attach an object at the other. [ 1 ] It works in accordance with Hooke's Law , which states that the force needed to extend or compress a spring by some distance scales linearly with ...
The balance spring is a fine spiral or helical torsion spring used in mechanical watches, alarm clocks, kitchen timers, marine chronometers, and other timekeeping mechanisms to control the rate of oscillation of the balance wheel. The balance spring is an essential adjunct to the balance wheel, causing it to oscillate back and forth. The ...
A Jolly balance from 1913. The Jolly balance is an instrument for determining specific gravities. Invented by the German physicist Philipp von Jolly in 1864, [1] it consists of a spring fastened at the top to a movable arm. At the lower end, the spring is provided with two small pans, one suspended beneath the other.
The North American Single-footing Horse, also called the Single-footing Horse or Single-footer, is a horse breed originating in the southern United States.The term "single-foot" refers to an intermediate ambling gait, sometimes alternately called the rack or paso largo, where the horse lifts each foot up separately and puts it down alone.
Thus, a cycle may be short, totaling approximately 3 weeks. [21] Horses mate in spring and summer; autumn is a transition time, and anestrus occurs during winter. A feature of the fertility cycle of horses and other large herd animals is that it is usually affected by the seasons. The number of hours daily that light enters the eye of the ...
In Picking Winners, Beyer claimed a breakthrough when a study of claiming races at Calder Race Course showed Beyer that 1:13 for six furlongs was equally fast to 1:26.1 at seven; from there, Kovitz's math was used to generate perfectly accurate parallel-time and beaten-lengths charts, which Beyer then used to make par times for classes, against ...

The average horse is healthiest with a body condition score between 4 and 6 (breed dependent), which indicates that the horse has a proper balance of feed to exercise. [8] An easy keeper or hard keeper should be watched closely as it is prone to either being overweight or underweight, respectively.
