What is the spring of constant strength?

In most types of strands, the force is developed when spring is compressed and then relaxed is proportional to the distance it has been stretched. Spring with constant force, unlike an ordinary spring, does not listen to this rule. As a result of physical design in the spring with constant force, the power that is reflected remains constant. Springs with constant force are therefore useful in many applications where consistent back force is important. This Act states that the power of the return spring in the direction of the backward character equals the distance of the spring from the equilibrium - in other words, how far it was stretched - multiplied by the mathematical constant, the speed of the spring. Spring is back in the direction of the opposite in which it was stretched. Because many elastic materials behave in this way, Hooke's law has a wide application of the area of ​​physics.

Hooke's law does not apply to springs with constant force because their power of the retrievalThe character remains constant in the range of movement. This is achieved by their unique physical design, which consists of thin, curled ribbons of steel. Springs with constant force lies in a state of relaxation when they are fully rolled up and are charged with force when they are partially or completely developed. After releasing the spring reverse weight lifting by pulling the extended ribbon back to a tight role. Since the power of the backward character usually comes closely closest to the curled cylinder, a constant force is maintained.

Common use of spring with constant force can be seen in tape measures used in applications and household construction. The typical tape measurement mechanism consists of a thin metal ribbon curled around the inner drum inside the plastic shell. When the measuring tape is pulled and locked, the strength is passed in the spring. When the lock is released, the ribbon is automatically inserted back into the plastic jacket. This pulling is achieved due to the effect of the backward character that acts as a spring of constant force.

mThe other devices that have automatic pulling also use the spring of constant power. Some examples include automotive seat belts, windows, seats of seats and stapling weapons. In all these applications, the power of generating the device must be consistent and always behaves in a small space in the same way. Springs with constant strength meet both conditions because they develop constant strength and can also be firmly curled, and to a slight size adapts to the large length of the ribbon.
