Determination of Young’s modulus by studying the flexural vibrations of a bar: experimental and theoretical approaches

Abstract: An experimental method has been devised to study the flexural vibrations of a bar to accurately determine the Young's modulus of its material. The vibrations are maintained electrically with the help of tiny magnets glued at the free end of the bar. The distinctive element in the present work is the determination of higher resonant frequencies with notable accuracy along with the fundamental. The actual values of the resonant frequencies in zero magnet-mass condition are obtained from the extrapolated plots of the observed resonant frequencies versus the mass of the magnet. A theoretical model is also developed for the fundamental mode based upon which numerical results are obtained and found to be in conformity with these experimental findings.

A Hybrid Heuristic for Restricted 4-Dimensional TSP (r-4DTSP)

Abstract: In this paper, we proposed a hybridized soft computing technique to solve a restricted 4-dimensional TSP (r-4DTSP) where different paths with various numbers of conveyances are available to travel between two cities. Here, some restrictions on paths and conveyances are imposed. The algorithm is a hybridization of genetic algorithm (GA) and swap operator-based particle swarm optimization (PSO). The initial solutions are produced by proposed GA which used as swarm in PSO. The said hybrid algorithm (GA-PSO) is tested against some test functions, and efficiency of the proposed algorithm is established. The r-4DTSPs are considered with crisp costs. The models are illustrated with some numerical data.
