Customized OEM Overload Coil Springs Black Zinc Plating Tension Spring
Describe:Extension springs supply a force by extending or pulling on them. Typically they are cylindrical helical springs made out round wire and have either machine loops or cross center loops. However they can be made conical, oval, barrel or virtually any other shape. The ends can be plane, extended, square or anything else you can imagine.
Tension spring, suitable for high and low temperature, corrosion resistance and other working environment, materials mainly include stainless steel spring wire, carbon steel wire, oil quenching and tempering alloy spring wire, high and low temperature alloy spring wire.

1. Do compression springs resist a pulling force?
A: Compression Springs are usually open coiled springs offering resistance from an applied force. Many shapes and sizes are available. Such as straight, conical, concave and convex , and many other designs to fit your needs. Ends can be closed or open, ground or unground.
2. Which spring is used in mechanical toys?
A: Spiral springs are used in watches and toys. Whereas torsion springs are used in places where a static position is required to be maintained against impact and load fluctuation.
3. What is tension formula?
A: Tension formula is articulated as. T=mg+ma. Where, T= tension (N or kg-m/s2) g = acceleration due to gravity (9.8 m/s2)
4. What is the formula of tension in a string?
A: We can think of a tension in a given rope as T = (m × g) + (m × a), where "g" is the acceleration due to gravity of any objects the rope is supporting and "a" is any other acceleration on any objects the rope is supporting.
5. What type of force is tension?
A:The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.
