Torsion Of A Spiral Spring Apparatus

Product Description

Description of DIDACTorsion of Spiral Spring ApparatusTorsion of Spiral Spring ApparatusSpiral springs are used to provide a resisting or restoring torque to a shaft when it is rotated through an angular displacement. They exhibit similar stiffness characteristics to linear springs, except that the effect is one of torque rather than force. The stiffness of a spiral spring depends on its physical dimensions and the rigidity of the steel strip from which it is formed. With the Torsion of Spiral Spring Apparatus student can easily calculate the theoretical stiffness of the spring, and compare the value with simple experimental results. The wall mounted unit consists of a spiral spring coiled from a length of steel strip. One end of the spring is attached to a shaft mounted in ball bearings. A load hanger and calibrated weights is used to incrementally load the spring. Spring deflection is measured with an attached scale.Specifications ofTorsion of Spiral Spring ApparatusSpiral springs are used to provide a resisting or restoring torque to a shaft when it is rotated through an angular displacement.
