Ao Fei immediately gave an embarrassed smile. The functions of these two platform scales were indeed rather obvious, though of course that was also because the Chieftain was knowledgeable and talented. At least, no one else had guessed what they were for.
"The principles of the balance and lever were things I taught you as well. The construction and principles of the Steelyard Beam and Scale Weight were also taught by me."
Luo Chong could not help complaining. This really fulfills that idiom—trying to wield an axe before Lu Ban's door.
Wen Nong also laughed from the side and said, "Then, Chieftain, give us your appraisal and see whether this platform scale still needs any improvements."
"Hmm, let me take a look first." Luo Chong nodded and began examining it carefully.
These two platform scales were, in fact, no different from the platform scales Luo Chong had seen in his previous life. After all, they used the same principle: the principle of the lever.
The larger one had an Iron Plate beneath it for bearing heavy objects, where the item to be weighed was placed. Directly in front stood a pillar, with a cantilever on its side. A platform for placing weights sat atop the cantilever's support. Beneath the support was a graduated Iron Ruler, with a tray hanging from one end for adding Scale Weights.
The principle behind this thing was essentially that of an enlarged hand-held Steelyard Beam. The weighing pan had merely been turned into an enlarged Iron Plate, and the Iron Ruler—the graduated "Steelyard Beam"—was pulled by a hook. On the other side, the Scale Weight that fixed the beam's weight had been changed into Scale Weights that could have more weight added. A Sliding Weight had also been fitted onto the "Steelyard Beam," allowing it
