WIRLING OF SHAFT APPARATUS
NaugraLabs Laboratory Product Name: WIRLING OF SHAFT APPARATUS
NaugraLabs Laboratory Product Code: Theory-0009

Description and Specification for Lab Tenders

WIRLING OF SHAFT APPARATUS.

DESCRIPTION
The unit consists of a base upon which bearing holders and driving motor is coupled. Bearing holder is provided for fitting various bearing to provide different conditions for test shafts, viz. both end fixed and one end free. A variac provided for speed control of driving motor. The unit demonstrates the phenomenon of whirling of shaft. After the test shaft cannot be used, hence unit only demonstrate the principle.
