Hooked Double-Ended Brass Weight Set Of 9, 1 Each

The Hooked Double-Ended Brass Weight Set Of 9 by United Scientific is a set of nine polished brass masses from 10 g to 1,000 g, 2,100 g in total, in a storage block. Each mass has a double-ended hooked rod and a flat countersunk bottom, so it can sit on a balance pan or hang in tandem with others. Physics teachers use it for lever-arm, moments and balance demonstrations.
