Conclusions A cost-effective experiment to demonstrate the gyroscopic effect was found to yield results with good accuracy. The experiment was easy to conduct and should contribute much towards the experiential understanding of the gyroscopic effect.
Conclusion In this paper, the performances of conventional incandescent and discharge lamps in photoelasticity are compared with LED devices. LED devices are found to have superior luminous efficacy, lamp life and flash response. Although the spectral bandwith of LEDs is broader than that of sodium discharge lamps, they are within the 100 nm limit necessary to ensure measurement accuracy. LED devices...
