6-Piece Steel Spring Set with Looped Ends

This set of 6 steel springs features looped ends for easy attachment to hooks, masses, and other apparatus. The springs vary in size, offering a range of spring constants for comparative experiments. Compressed spring dimensions are: 6.25 x 0.5 inches, 8 x 0.6 inches, 6.5 x 0.75 inches, 7.5 x 0.6 inches, 8.25 x 1 inches, and 9 x 0.4 inches. Flexible lengths range from approximately 10-20cm. The variety of spring rates allows students to investigate Hooke's law by comparing force-extension relationships across different springs, determining spring constants, and exploring elastic potential energy. Made from durable steel for reliable performance across many classroom sessions.
