The Application of Virtual Tools in Teaching Dynamics in Engineering

Abstract

Student success in Dynamics, a core subject in Mechanical Engineering courses, requires conceptual understanding of complex systems. Dynamics covers motion of particles and objects, and usually relies on 2 dimensional images and/or written descriptions to explain models and problems. This paper explores the value of visual representation of Dynamics problems with an assumption that it would facilitate student understanding of the content. Two approaches were applied for representation of Dynamics problems with the premise of Bring Your Own Device (BYOD): used with augmented reality and web animation activities. Responses from students and reflection from lecturers were collected and reviewed in relation to the applicability and the ease of use. Students and lecturers both appreciated the benefits of visual representation of complex models, and the possibility of manipulating with virtual objects. Lecturers also appreciated the easy access and use of tools during the class.

Application of CAE technology in the experimental teaching of metal tension and compression

“…Fig 2(b) shows the cast iron in compression with cracks inclined at 45° angle. The compression cast iron experiment allows students to understand the problems that can occur during the compression of cast iron [6] . Demonstrations of experiments increase students' interest in learning.…”
