How does a spring work in a balance?
The balance contains a spring which provides a measure of the force applied to the balance. The larger the force, the more the spring extends, with the force level indicated by the scale on the balance.
How is the Newton spring balance used in everyday life?
The Newton spring balance is used to measure force. This is achieved using a law known as Hooke’s law. The importance of this law may not be obvious to you, but it is used in the design of most items you use every day.
When do Springs lose tension, do you replace them?
As a result, the spring is weakened, sometimes even to the point where it does not function at all and must be replaced. To avoid spring weakening due to creep, minimize stress on your springs whenever possible. Do not leave your springs under constant compression unless this is required for them to do their job.
How is the spring constant of a spring calculated?
The spring constant is calculated by calculating the slope of the line in the force vs spring extension graph. This gives Hooke’s law for this Newton spring balance as “applied spring force” equals 0.1 times the “spring extension”. It is a unique property of this Newton spring balance since all springs have a unique spring constant.
How is the outer turn of a balance spring fixed?
A narrow slot is formed on one end of the regulator by two downward projecting pins, called curb pins, or by a curb pin and a pin with a heavier section called a boot. The end of the outer turn of the balance spring is fixed in a stud which is secured to the balance cock. The outer turn of the spring then passes through the regulator slot.

What happens to a spring when it is under stress?
A spring under tension for an extended period of time can become weaker. Any object will either resist or deform when subjected to outside stress. Springs are specifically designed to deform in order to absorb energy from outside stress, then return to their natural state when they release that energy.
How does a spring have to be durable?
If a spring is to be durable, the stress in the material must not be greater than the strength of the material permits. When a load is applied to a piece of metal, it must deflect first elastically, and if the load is high enough, it will also do this plastically.
