This aluminum demonstration balance support stands 18.5cm tall and weighs approximately 280g. The sturdy, notched support is designed for use with a meter stick, mass hangers, masses, and knife-edge clamps (all available separately) to assemble a complete balance apparatus. The notched design holds the meter stick securely for balance demonstrations. This support provides a hands-on way for students to explore torque, equilibrium, and the lever principle in physics classrooms.
