Students can gain an understanding of Hooke’s Law and of the significance of the spring constant with this versatile set.

• Short, Transparent Ruler for Parallax-Free Scale Readings
• Five Springs with Hooks and Markers
• Meter Stick Scale with Clamp and Suspension Hook
• Mass Hanger
• Set Explores Hooke's Law

The five springs have constants of approximately 2.5, 5, 10, 15, and 25 N/m for comparison study. Each is equipped with a lightweight aluminum hook fitted with a sliding position marker for reading length changes. A meter-stick scale is fitted with a suspension hook and clamp for easy setup.

Springs are 1.4—1.9 dia. x 5.2—7.5 cm with 7 cm long hooks. The scale and clamp measure 5.5 x 7 x 100 cm. Additional stiff springs and weak springs are also available separately. The stiff spring constant is 46 N/m, and the elastic limit is 6.6 Kg (3 lb.). The weak spring constant is 1.56 N/m, and the elastic limit is 142 g (5 oz.).
