1. What is a tension spring?
A: Tension springs are wound helical coils that are wrapped tightly together to create tension. Also called extension springs, tension springs provide extended force when the spring is pulled apart from its original length.
2. What is the difference between a compression spring and a tension spring?
A: Although a tension and compression spring are both helical coiled springs, the difference in their functionality and purpose can be significant. In essence, tension springs are designed to bring components together, whilst compression springs are made to keep components apart.
3. What is the formula for tension of a spring?
A: F = -kx. The proportional constant k is called the spring constant. It is a measure of the spring's stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction.
4. Is tension a spring force?
A: Tension denotes the energy stored in the spring (assuming it is a tension spring). Spring force is release and utilization of this energy for a specific purpose.n towards its equilibrium position.
5. What is a tension spring on a sewing machine?
A: The bobbin or lower tension, as it is sometimes referred to, is adjusted by tightening a screw against a flat spring and the spring, in turn, pinches the thread leaving the bobbin creating the tension needed to manage the loops and balance the stitch.
