At the recent paper car building event held at KMUTT's KX Knowledge Exchange, participants successfully assembled over 20 paper cars. The collaborative effort involved working alongside Renzo Sy, a representative from F1 in Schools, mentoring more than 60 students at the KX Knowledge Exchange centre. Together, they delved into the intricacies of car mechanisms, focusing on designing optimal axle sizes and wheeling systems. Additionally, the event provided a valuable learning opportunity as students received instruction on the principles of aerodynamics, particularly in relation to airflow dynamics. The combination of hands-on building and theoretical lessons contributed to a comprehensive and engaging experience for all involved.
