Abstract

Using hands-on experiments in the classroom is a highly effective way to deepen students' understanding of theoretical concepts. By researching and developing a practical and cost-effective experiment using a pitot tube, we can transform the teaching of fluid mechanics from a content-based approach to one that promotes competency and practical application. The research includes exploring pitot tube theory, developing and evaluating the experimental design, simulating flow through the designed pitot tube using computational fluid dynamics simulation software, and implementing and evaluating learner satisfaction. The feedback we received from the students showed high satisfaction with the practical equipment used in the classroom and confirmed that this hands-on approach helped them achieve their learning objectives.

Abstract

The oscillation of hoisting masses in bridge cranes significantly impacts system stability, resulting in adverse effects such as excessive dynamic loads, inaccurate positioning during loading and unloading, and overall instability. Therefore, the angular oscillation of the hoisting mass must be controlled in the design of bridge cranes. This paper presents a mathematical model for the analysis of the angular oscillation of a hoisting load, both during oscillation and trolley movement. The MATLAB/Simulink software was used to simulate the dynamic behavior of the model to gain insights into the oscillation angle and its limitations. The results substantiate the reliability of the proposed model for predicting the angular oscillation of hoisting loads in bridge cranes.
