The Mechanics of the Human Body is an important course that links the principles of mechanics to the movements of various parts of the human body. In this study, we analyzed the quadriceps force during both static and dynamic leg extensions, the deltoid force during arm abduction, and the tendon forces within the musculoskeletal system. Building on these studies, we developed an innovative teaching approach for the course Mechanics and the Human Body, integrating physical prototypes with interactive simulations. 3D-printed leg and arm models were designed to replicate leg and arm extensions while lifting a force. To address the limitations of physical models, we enforced animations and interactive simulation tools using Python and JavaScript. The simulations were uploaded to platforms to give easy access to students, and these enabled students to manipulate variables and visualize changes in tendon and muscle forces in real time. We also extended our analysis to investigate how deltoid force is affected when a person wears a heavy suit, such as a NASA space suit. This blended strategy enhances conceptual understanding of biomechanics by combining tactile and visual modes of learning. Student feedback highlighted that these demonstrations made abstract mechanics concepts more concrete, fostered interdisciplinary engagement, and improved comprehension. Our findings illustrate how merging biomechanics research with educational technology can transform physics education for students in physical therapy, exercise science, occupational therapy, pre-medicine, and related fields.
