The R-101 Low Cost Mechanical Educational Shake Table is a 1 DOF teaching tool used for the demonstration of modes and resonant frequencies of structures. It allows students to perform experiments on several test structures so that they understand different structural responses resulting from earthquake motion. In addition, instructors can help students to learn about the effectiveness of proper design versus inadequate design in safety measures. It is purely a mechanical system that can be easily mounted to a lab surface or floor. A user manual is also supplied with the equipment that includes five suggested educational experiments and some quizzes to assess student comprehension.
