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 ...
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 driver would either stand in the cart, sit on the load, or walk beside the horse. [5] [6] In America, many vehicles had unsprung bodies, but instead were constructed with a sprung driving seat. [2] Starting in the late-1700s in England, taxes were assessed on horses, wagons, carts, carriages and coaches. Conveyances with springs were taxed ...
The Henneke horse body condition scoring system is a numerical scale used to evaluate the amount of fat on a horse's body. It was developed in the early 1980s by Don Henneke at Texas A&M University with the goal of creating a universal scale to assess horses' bodyweight, [1] and was first published in 1983. [2]
A balance spring, or hairspring, is a spring attached to the balance wheel in mechanical timepieces. It causes the balance wheel to oscillate with a resonant frequency when the timepiece is running, which controls the speed at which the wheels of the timepiece turn, thus the rate of movement of the hands.
The Single-footing Horse is a medium-sized breed of light riding horse. It is primarily known for its intermediate four-beat gait, which may range from 7 to 9 miles per hour on a trail ride to over 15 miles per hour at a road speed. [2] High speeds in excess of 20 mph have been recorded. [3]
A steelyard balance, steelyard, or stilyard is a straight-beam balance with arms of unequal length. It incorporates a counterweight which slides along the longer arm to counterbalance the load and indicate its weight. A steelyard is also known as a Roman steelyard or Roman balance. A 19th-century steelyard crane
The American Stud Book is the stud book for the Thoroughbred horse in the United States. It was founded by Sanders Bruce, with assistance from his brother B. G. Bruce in 1868. [1] In 1896, the Jockey Club bought out Bruce and assumed publication of the book, which it has continued to the present. [2]
