Vibration of Spiral Spring Apparatus
Product Code : EL-AMLE-10641
Quick Answer : This apparatus investigates vibrations on a spiral spring-rotating mass system, built around a shaft carrying a spiral spring – a metallic strip wound around a rod at one point – mounted on ball bearings with an integrated angle measuring scale to read the shaft's rotation. A metallic rod fitted with two sliding weights at its edges is used to deflect the shaft, and the deflection can be measured through a protractor together with the extent of the initial deflection, letting the unit determine the time period and frequency of the spiral spring. The spiral spring itself has a stiffness of c=238Nmm, a 10x1mm cross-section, an effective length of approx. 800mm, and inside/outside radii of 10mm and 50mm, all mounted on a 200x250mm base plate.
Spiral spring is a type of spring which is formed by a metallic strip wound around a rod at one point. The apparatus consists of a shaft on which the spiral spring is attached, and a metallic rod, containing masses at its edges, is used to deflect the shaft. The deflection can be measured through a protractor, and the extent to which the spring was deflected initially can also be found; this unit is designed to determine the time period of the spiral spring and its frequency.
