0 a device for measuring the weight of something by putting it into a small dish that hangs from one end of a straight bar and balancing it with weights at the other end -- 槓桿秤（用於測量重量的工具，將所測物放入槓杆一端的托盤中，並用另一端的重物加以測量）
Unfor tunately, the energy balance was predicted to be 2%; however the actual delivered beam balance was 11%.
For high precision work, the center beam balance is still one of the most accurate technologies available, and is commonly used for calibrating test weights.
In old days, weighing was done with a beam balance to make equal splits.
Aerodynamic forces on the test model are usually measured with beam balances, connected to the test model with beams, strings, or cables.
In order to measure the aerodynamic forces on the whole model, beam balances are connected to the model.
