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 stiffness of the spring, its spring coefficient, in N·m/radian^2, along with the balance wheel's moment of inertia, in kg·m 2, determines the wheel's oscillation period. The equations of motion for the balance are derived from the angular form of Hooke's law and the angular form of Newton's second law: τ = − κ θ = I α ...
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 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]
Balance wheel in a 1950s alarm clock, the Apollo, by Lux Mfg. Co. showing the balance spring (1) and regulator (2) Modern balance wheel in a watch movement A balance wheel , or balance , is the timekeeping device used in mechanical watches and small clocks , analogous to the pendulum in a pendulum clock .
Bull neck is fairly common, especially in draft breeds, Quarter Horses, and Morgans. Bull neck makes it more difficult to maintain balance if the rider is large and heavy or out of balance, which causes the horse to fall onto its forehand. Without a rider, the horse usually balances well.
