Parts and their functions

• Steel wire, 1.5 m (इस्पात का तार, 1.5 m) — Carries both blocks: T = 10 × 9.8 = 98 N. ΔL = TL/(AY) = 98 × 1.5/(4.91 × 10⁻⁶ × 2.0 × 10¹¹) ≈ 1.5 × 10⁻⁴ m.
• 4.0 kg block (4.0 kg गुटका) — Hangs between the two wires.
• Brass wire, 1.0 m (पीतल का तार, 1.0 m) — Carries only 6 kg: T = 58.8 N. With Y ≈ 0.91 × 10¹¹ Pa, ΔL ≈ 1.3 × 10⁻⁴ m.
• 6.0 kg block (6.0 kg गुटका) — Diameter of both wires 0.25 cm ⇒ A = 4.91 × 10⁻⁶ m².
